I'm not sure how a 23 year old can have 4 years of eligibility, but I'll trust you.However, a 24 year old Div I College O-Lineman should be able to bench MUCH more than 315 and clean more than 235, which you already know. How many reps can you do with 225? I'm 6'3" / 245lbs and can do 22-25 reps, with a Bench Press 1RM of 385. Your squat and deadlift numbers are good though, and I'm jealous!
I would recommend concentrating on your weaker lifts. Bench Press is a fundamental necessity, as much as footwork and arm technique. 10 reps with your body weight is a good goal to start with. If you decide to supplement with gear, then you will be able to achieve that. Good luck to you!
