The thing is, these "slight variations" make a big difference in whether it's a pro-style offense. When you start getting QBs and linemen used to doing things they won't do at the next level (shotgun all the time or huge splits), it's a bigger and harder adjustment for them when they get to the NFL. That goes completely against what we're trying to do here, which is to prepare people for the NFL and put them in positions where it's easy for scouts to project them to the NFL. Regardless of how "bland" the NFL is, kids want to get there and it's our style of offense, not Leach's, that helps them do it. Leach's offense really didn't help the NFL prospects for pretty much anyone; Crabtree went high in the draft but would have gone higher had he played in a pro-style offense. Leach's offense does almost nothing but hurt NFL aspirations, which leads to my comment about "throwing them down the drain."
