substitutions, and team control

[coachferrier]

OK, maybe I just missed the boat on this--but is there a way to do mass subs? Like if you're in a blowout, would it be possible to sub in a whole new group of guys?
Or if you are letting the cpu play against the cpu, the first string guys stay in the whole game and I just had an 8 man game end up 192 to 14.

also--I like how in other games you can play parts of the game and let the computer control the rest.

I dont have the attention span to sit there and call every play on defense, especially since I'm an offense guy and I just really want the ball back more than anything.
Is there a way to make it so you could, say, be the offensive or defensive coordinator only? Or something to that effect?
