Your average college ball player for a top end school pulls around 600-700, benches 400-500, and squats 600-800lbs.
Those are the average numbers for D-1 high major lineman. These guys have the best genetics, thats why they are recruited and on scholarship. Lots of naturally huge, really strong guys-BUT, also lots of juice-especially the BCS conference schools. They take the raw material good frame, 6-5 kid who was a TE/LB/FB in high school but is too slow to play that position in the bigten, sec etc-they get him on the juice, a kid i grew up with was pressured to get on the juice by a bigten school.
The guys physique is obtainable naturally, with good genetics-but its hard to say, so many of these guys are on a cycle.
