If the biggest argument for killing this league and going back to the yahoo league is that they're now about the same, i guess I don't see how it's worth the hassle. Not really a lot of difference between the two at this point, so what's the basis for liking one enough to change? Unless Yahoo has gotten a lot looser about things, ESPN's benefit was that you could really customize the league a lot more, and do divisions, schedule, rules, etc.
Biggest reason I did ESPN this year is because the Keeper league is already there, so for anyone (like myself) doing both leagues, you can manage the whole thing from one location. It's certainly a big time saver for me with baseball, and would prefer to do the same for football.
If someone wants to change over that badly, they're more than welcome to start that league and talk people into changing, but if that's the case, i'm going to pass on the yearly league and just do the keeper league with you guys. too much effort...
