1) Guys you wouldn't know are on the football team b/c their best friends at school aren't on the football team.
2) Players that socialize equally with athletes & non-athletes, but if you run into them they are most likely with other football players.
3) Guys who rarely socialize with non-football players.
In my experience, 75-80% of the players fall into categories 1 & 2. Some guys, for whatever reason, don't care to be part of the regular student body. They typically aren't mean to "regular" students, but it is a shock if you see them with someone other than a football player.
