Have you ever seen the schedule for a D1 football player? It may not be "class" heavy but it's loaded
Fall semester load is rather brutal to be honest.
With the limited time the coaches can spend with the players (and are restricted from coaching them at times of the year), the guys take it upon themselves to get together and work on the things they need to work on. I'm sure there are varying degrees to the amount of work being done at different programs across the country but I know the QBs and WRs for Akron have put in significant time together this offseason.
Where the heck is the fun in giving up Madden/bonding time?
