D2 Football is Division 2 championship. They usually create a second division for when they very many teams. Usually teams are put into the second division because they were relegated or promoted. An example of this is the NPower Championship, where the bottom 3 teams are relegated from the Premier League and put into the second division. Cheers
The majority if not all of them definitely take steroids especailly in d1 and d2 college football.
Yes, they're d2 so they have athletic scholarships
Mostly D1, unless there are players which truly stand out in D2 or D3.
