Any sound defensive strategy attempts to stop the run and pass. Not sure it develops bad tendencies for any position. Repetitions against quality competition allows the coaching staff to correct errors.

 

I've seen some treat 7on7 like Madden running slants and streaks.

IMO 7 on 7 is geared towards offense and when executed correctly can be very beneficial for your team. Drawing in the dirt to win is obviously not very productive or conducive to the grand scheme, but lets look at some stats from the last two years:

 

UK 7 on 7 -2013- Final Three- Collins (State Champs 13-2), Henry Clay (9-3), Lou. Male (12-2)

Nelson County 7 on 7- 2014- Final Four- Central Hardin (12-1), Lou. Male (11-1), Bullitt Central (9-3), Iroquois (11-2)

Southern 7 on 7- 2014- Final Three- DeSales (State Champs 14-1), South Oldham (8-3), Bullitt Central (9-3)

 

Looks like winning teams are participating in 7 on 7 and being successful. **drops mic**
