Ignoratio,
I think you have a fallacy in logic by reasoning that because a 30 man roster has the highest percentage chance of winning, MY best chances of winning are to have a 30 man roster. When you select YOUR roster, you are trying to maximize YOUR chances of winning. At the end of the day, if you could isolate roster size as the only variable, then the results from year-to-year would matter in analyzing the impact of roster size on results, and your logic would be sound. There is no way to do that though, because things like player selection, player distribution, and salary distribution can't be removed from the calculus.
When I discuss roster size selections, I'm sort of assuming relatively normal player and salary distributions. I think 30-man rosters are better than 18-man rosters, but I wouldn't say that a 30-man roster with 22 defenses was better than a well-constructed 18-man roster.As I've said re: player selection, I think that is an overrated component, which I'll discuss more below.
I agree that luck plays a huge component in this contest. It's not different in fantasy football in general -- make the playoffs and hope you get hot and/or don't run into a buzzsaw. That said, you don't for one second truly believe that skill doesn't play some role. If you did, you would just pick a random roster each year. The question of the amount of the relative importance of luck and skill is certainly debatable, but I don't believe that anyone can realistically argue that skill has nothing to do with it.
I think there is definitely
some element of skill in fantasy football, although it's not nearly as much as most people like to think. The "skill" people claim to exhibit is typically just a combination of randomness and memory biases. If anyone could reliably predict fantasy performance, they should start a website and make a fortune, because none of the experts I'm aware of in the current market have a record that indicates they're much better than anyone else.Besides, knowing when to draft which positions, who to start each week, when to cut ties with a player and how much to spend on his replacement in blind bidding, knowing how and when to make trades, etc., those are the kinds of things that a "skilled" owner will do better than a relatively unskilled owner. None of that, however, comes into play in this contest. In normal fantasy football, you don't pick a roster in August and hope they score a bunch of points in weeks 14-16, and surely you don't think that anyone actually has the skill to do so accurately.
I don't think that the degree of skill that matters is particularly apparent between most of the folks who care enough about this contest to study and analyze their rosters. I do, however, think that out of the thousands of rosters submitted a huge percentage of them were doomed from the start. Be it because of comical reasons some have identified on this thread, or more mundane reasons. Mine was one of those doomed rosters more than once in the past. I'll bet dollars to doughnuts that those doomed rosters occur at a higher rate in smaller rosters. No, I don't have any empirical evidence to support that, but it seems intuitive to me -- it just takes less effort to pick a smaller roster than a larger roster.
I agree. We've attempted to look at this in the past, and it does seem that there are proportionately more "junk" entries among the small rosters than there are among the large rosters. But that has nothing to do with skill in player selection, that just has to do with skill in roster construction.
Additionally, having knowledge of the role/skill/ability of lower-dollar players is not commonplace. Indeed, I readily acknowledge that some on this thread almost certainly have a higher skill level than me with regard to identifying those lower-dollar players worth rostering.
After that verbose narrative, I had to select my roster based upon my skills. I had little confidence in my ability to reach deep down into the player pool. I felt that I had a significantly higher probability of selecting a competitive roster comprised of 18-21 or so players. If I put together a 28-30 man roster, I would simply be shrugging my shoulders at the start of the season and simply hoping to get lucky. I'm still hoping to get lucky, but I feel that the amount of luck I need is less than it would have been if I had a bunch of players who were little more than random guesses on my part.
That's certainly not to say that you, or anyone else, don't have a higher skill level at choosing those cheaper players than me. The fact that you have that skill does not mean that I would fare better by matching your roster size. The "pick random cheap guys and they'll always beat your expense alternative" arguments are what I'm interested in exploring, because if that's true then I simply need to pick 1 or 2 high-dollar player(s) next year and replace them with 6-12 cheap alternatives.
I don't claim that anyone has a higher skill level at choosing cheaper players. Now, the reason cheaper players emerge with value is because their prices are set in early August but the rosters aren't due until September. Due to this, cheaper players are often perceived to be underpriced (2010 Arian Foster is the most obvious example of this phenomenon). But it doesn't require any special "skill" to identify those players. I mentioned early in the thread that due to real life getting in the way, I spent very little time doing my own research, and pretty much just selected all the guys that were getting hyped by FBGs. It's not like you have to research deep on your cheatsheet to figure out who the gems are if you don't want to; if you're doing the basic level of fantasy preparation, you're probably going to know who all these "sleepers" are because everyone's talking about them.The thing is, it's not that you're bad at picking cheap players. It's that you're overestimating your ability to select expensive players relative to your ability to select cheaper players. You think you're better at picking expensive players than you are at picking cheaper players. I disagree. We've all heard the stats - 50% of first round fantasy picks are busts, etc. Again, it's mostly confirmatory memory biases that make people think they're good at fantasy football. Like I said, if any of us were
actually good at figuring out which expensive players would perform as expected and which wouldn't (instead of just
thinking we're good at it), we could make a lot of money with that skill.
Now, more importantly, even if you
are more skilled at picking expensive players, that's only based on season-total projections. You do not have the skill to project which WR2 will score the most points in week 7 when your WR1 is on bye. You do not have the skill to forecast that your RB corps will score less than average in week 9 and subsequently choose a TE flex that will make up the difference that week. No one does. The flaw with small rosters is that, even if you pick a bunch of great players, they're still going to have normal up and down weeks and those normal down weeks are too great a risk when you have all your eggs in so few baskets.
That's why larger rosters are better than smaller rosters. I don't dispute that the average quality of players on smaller rosters is probably better than the quality of players on large rosters, but small rosters just lack depth. No matter how good your players are, that's a fundamental flaw in roster construction.
My argument actually is that if you replaced 1-2 expensive players with 6-12 cheap alternative you'd improve your team. Precisely because you can't predict weekly performance (whether you choose expensive players or cheaper players) you need to use quantity to your advantage in the best ball format. I don't advocate choosing those 6-12 cheap players completely randomly, but it doesn't require any more skill to figure out who to pick from - when I was picking my roster, I didn't know who most of the cheap players even were. I picked the ones that I did know because everyone was talking about them. If you want to do more or less research than that, that's fine - since I don't think we're really that skilled in projecting fantasy performance, I don't think it makes much of a difference.
