BIO: All-conference selection as a senior after posting 59/19/6. Junior totals were 46/11/2 after 43/11/4 as a sophomore.
POSITIVES: Hard-working, interior prospect who lacks the great size-speed numbers for the next level. Plays with good lean, quick through the gaps and displays lower-body leg drive. Gives top effort until the whistle blows. Mentally alert and immediately locates the action.
NEGATIVES: Ducks his head, takes himself out of the action and lacks body control. Does not pursue laterally with speed and lacks adjustment. Easily ridden from his angle of attack.
ANALYSIS: Tough and competitive, O'Brien is a prospect that uses all his tools to the fullest of his ability. Though he had a good week of practice at the Blue-Gray Game a camp player that will not be drafted.
