Great thread. I prefer the flexbone spread option because, like others have mentioned, it is much more conducive to power running and is much more efficient in short yardage while still getting tons of big plays. I also like that it is unique, because I think it's foolish to think that we will beat more talented teams by doing the same thing they are doing.
That said, I've got two issues with our current scheme:
1) Lack of a passing game. It's not that the scheme prevents us from passing, but for some reason we are awful at it. I'm not sure how much is related to the scheme, how much is related to lack of practice passing, or how much is related to the players, but we have GOT to be able to capitalize on passing opportunities to make this scheme truly viable.
2) Negative effects on recruiting. I really have no way of knowing how much of an actual effect our scheme has on recruiting, but we can't afford to handicap ourselves much more. I don't know what to think about this one, or if going to another unique scheme would really be any better.
IMO if we fix EITHER issue, the other could soon fix itself. I've had faith that PJ would fix it, but he's had a lot of time. I really like the guy, but I think he gets one more year to AT LEAST show a positive trend in recruiting and on the field product or we will be forced to move on. If that does happen, I would be willing to go in pretty much any direction except pro-style.
