With few exceptions, I'd rather start a running back than a receiver, and a receiver than a tight end. I think we can all agree that there are exceptions, but that this is true for the most part. Which is why I don't like the idea of being able to swap a back for a receiver - it doesn't change the value of running backs, it just allows teams that don't have them to survive. If you only have to start one back, but can start two, of course you're still going to want to start two backs if you can. So what happens is, people with good running backs horde them and won't trade them unless they get superstars or another running back in return. Which means that the draft is still a game of "get the best running backs" first and foremost, and then everything else. People were drafting backup running backs ahead of quality WRs in hopes of hitting the lottery when the starter went down. It changes the game from trying to figure out who the best players are, to guessing who will get hurt. Artificially changing the scoring requirements doesn't work well, either. Giving QBs 6 pts per TD makes sense, but what a lot of people don't remember is that the big reason the rule was changed from 6 points to 4 in many leagues in the first place was because Brett Favre was thowing 39 TDs while there were only a few others in the league throwing more than 20. Making those rare disparities even larger is ony a band-aid on a broken structure - you can reset the numbers so that they work better last year, but next year's numbers will throw everything off again, and when you make one position much stronger than the others, like by using 2pt TE receptions, you make it a game of "whose tight end blew up this week". We don't need to find a way to make people want start more receivers, or to draft QBs earlier. We don't need to make their scoring even out just to fit some strange sense of fairness. What we really want to do is give people a difficult decision during the draft and afterwards, and to reward people who make the right decisions. We wanted to make it so people had a viable reason to trade a running back for a receiver, or even for a tight end, without arbitrarily changing the rules to favor the other positions. The rule change that we made was based on a simple thought: While I'd rather start a back than a receiver, and a receiver than a tight end, if I had to choose between starting a back and a tight end, or two receivers, it becomes much more difficult to decide. So we implemented the following lineups: 1 RB 1 WR0 TE4 FLEX ** For each running back you use in a FLEX spot, you must also use another FLEX spot on a tight end. Which allows the following formations:3 RB1 WR2 TEor 2 RB3 WR1 TEor1 RB5 WRYou can also go with 2-2-2, or 1-4-1, or 1-3-2, or any other formation that follows the basic rule that you have to start a tight end if you start another running back. Guess which formation most people use? 2 RBs, 3 WRs, and 1 TE. Some people try to draft for the 3-1-2, but it's never won, because it's just too hard to get three good backs and two tight ends on the same team. And while you'd think people would try to draft 1-5-0, it's so difficult to get three good receivers when everyone wants good ones that you can't rely on that, either. Even the top teams have interesting lineup decisions every week - the league winner last year changed lineups every week, and used four different formations en route to his championship, because he had drafted enough depth that he was always able to play the hot hand and the good matchups. And injuries almost never knock a good completely out of contention, because if you've drafted quality depth, you can usually find a different formation to hold the fort. Another rule adjustment that goes along with it: We keep four players. So while you can build a quality team, you can never keep a perfect team together from year to year. We've had people break up a group of stud backs to keep one back and three top receivers because they figured they could get a back in the draft. We've had people draft a stud tight end in the first round over a quality running back because they'd kept two backs and a receiver. Last year, we had a guy take five running backs before he'd filled out his lineup, and then trade them throughout the season because he was struggling to stay in contention. The draft is unpredictable, because while some people draft to fill out their lineup, others draft breadth so they could play different formations, or depth so they can be as strong as possible in their preferred formation. The end results is that people, for the most part, take the best player available at each pick, regardless of position. And adding one last layer of complexity, players can only be kept three times before you have to release them back into the draft. At first, we were worried that this might encourage people to mortgage their future for next year or that the top contenders would be able to make a trade at the deadline that put them over the top. But that hasn't happened. Instead, it's increased trading because I might trade you one year of Manning for two years of Gates, or one year of Peterson for three years of Wayne. People will trade for a player who fits their formational needs, or their keeper eligibility, or the best player this year. I've tried a lot of leagues with a lot of rules over the years. This is easily my favorite.
