Big Picture Strategy Theory (1 Viewer)

Like many people here, I spend an inordinate amount of time debating between starting options each week. I've had a Eureka! moment and am curious what others' thoughts are on this line of thinking:

1) Most fantasy league scoring systems are heavily tilted toward touchdowns.

2) Markets tends to produce the most reliable information.

3) Point spreads are market based.

4) Points spreads can be used to predict game scores (subtract the point spread from the over/under to get the losing team's predited score).

5) All things being equal (role of player in the offense, in particular), a player on a team predicted to score more points is more likely to score one or more TDs than a player on a team predicted to score fewer points.

6) When in doubt, then, start the player on the team the point spread will score more points.

Example: I'm debate between Lee Evans and Calvin Johnson this week. The point spreads predict the Lions to score about 23 points and the Bills to score only 13-14. There's some difference in roles here (Johnson still the #2 WR), but my instinct is that 10 more points of likely offensive output for the Lions is enough to swing things toward Johnson.

Does this theory make sense. If not, where does the line of thinking break down?

For the most part, the FBG projections will mirror this system, as the projections sum to game outcomes very close to what the point spreads predict. But I'm inclined to use the point spread system to settle statistical ties generated by the FBG projections (projections within, say, one point of each other).

 
I would say it can be used as a tiebreaker for two even players, but nothing more. I mean even Vegas oddmakers get it wrong sometimes.

The oddsmakers may get it wrong, but once the line is posted the bettors will move them in the right direction. The point spreads are as good as any predictor out there--otherwise there'd be a bunch of people making a whole lot of money on a weekly basis.

:) I've done this for a long time. I like a RB on a team that is favored - and WR on teams that will probably be behind or games with a high O/U. As was stated, I usually only look at this when trying pick between to fairly even players.
 
...(subtract the point spread from the over/under to get the losing team's predited score)...
That doesn't look right to me. Wouldn't it be this:over/under divided by 2 - point spread divided by 2 = Loser's predicted scoreandover/under divided by 2 + point spread divided by 2 = Winner's predicted score

The problem with spreads early in the year is that the "market" doesn't have enough data to work with. We have a general idea of who the good offenses are and who the good defenses are, but these are inexact at best. With 3, 4, 5 weeks of data from all the teams matching up with different opponents and I start trusting point spreads a whole lot more. More data = more accurate.

 
I'll sometimes use point spreads to help pick a team defense in close cases, but that's about the only time. In general, if there's a big point spread difference across two games, my gut sense about which team is a bigger favorite will be right anyway, and I don't need to know the exact spreads.

Yes. I missed a step there. Subtract the point spread from the over/under and then divide by two to get the predicted losing team's predicted score. Then add the point spread to get the predicted winner's score.The math works out the same as your method. Just less division.USA Today's site has a good list of live odds.
 
i think this is pretty good strategy too - except i stick with the vegas opening line.

the problem with the strategy as i see it is that in the end a lot of the over/unders can be close together.

 
I think its genius. I'm going to start using his method. Saves a ton of time analyizing run defenses, pass defenses, historical matchups, weather etc.....makes it really simple yet useful.

i would second that.i trust the lines that they guys set in vegas much more so than the betting public. it's their livelihood. i'd trust the lines before the betting public has a chance to influence them.i don't regularly bet on football (i prefer horse racing), but of all the people i know that regularly bet on games, i'd say vegas is winning.about the specific questionusing game lines is part of a bigger strategy really. it's important to try to predict how the game will be played to help with fantasy decisions. it's a piece of the puzzle in trying to have RBs on teams that will be playing with the lead and QB/WRs on teams playing from behind.specifically, i wouldn't sit lee evans for calvin johnson. i doubt the bills will be able to run the ball, they'll be playing catch-up all game, and last i checked, champ bailey doesn't play for the steelers. i love calvin's talent and they'll be throwing the ball early and often, but lee's is explosive, more experienced, and in a similar matchup (imo). and last i checked, calvin was WR3 for the lions (for now)
 
I myself use this information as just another tool in the tool box.

It's true function should be pointed out to people whom might not understand the reason for the betting line. Its only function is to split the betting publics money evenly between the two sides or totals. Nothing more. By and large the betting public is stupid and uninformed favorite bettors. Linesmakers are not attempting to predict the outcome. They are trying to split the money. This being said, a smart line can split the money and be a very close aproximation of the outcome.

 
I always look at the vegas lines. Be aware, however, that DET is always expected to score more than BUF. You need to take the line with respect to what their line usually is. Evans rates to get a much higher proportion of the weaker offense's production comprared with Calvin Johnson. DET at home vs. MIN is probably above average for them, while BUF at PIT is way below average, so Evans should be moved down some while Johnson up some. The position that benefits the most from this analysis is Team defense. RB work best as the favorite, while QB and WR actually work better as an underdog. So while Evans loses value because the team is only expect to score 14 points, he gains some back because his team is a 10 point dog, so they are more likely than usual to abandon the run and throw the ball. This makes Lynch a particularly unattractive start.

 
With so much info out there, you'd be foolish not to go out and take a look at this.

You need to look at matchups, Run vs. Pass, etc. - but this is readily available info and it is unbiased due to market conditions (people bet both sides) - so why not?

BTW - vegasinsider.com is an excellent place to look for these, and free (just delayed 15 min but who cares)
