Also, you are allowed to allocate 180 minutes PER POSITION (less what you put into formations). As dream76 said, no more than 50-60 minutes in formations and Special Teams (total), then the rest for your positions. For example, here is what I have for my QBs on one of my teams (this is for a D1A team, for a DIII team, it should be more):
COND: 20 HNDS: 12 AGLTY: 15 PASSING: 25 STRNGTH: 20 STUDY FILM: 20
For my LBs:
COND: 22 TKLNG: 20 HNDS: 14 AGLTY: 15 STRNGTH: 20 STUDY FILM: 21
