Bio: Three-year starter at right tackle and guard. All-Conference selection after his junior and senior campaigns.
Pos: Massive blocker who eliminates defenders at the point of attack. Strong, walls opponents from the action or engulfs them altogether. Makes effective use of angles, keeps his feet moving throughout the action and possesses powerful hand punch. Does not give up an inch of room and easily anchors at the point.
Neg: Not quick or explosive into run blocks. Loses balance sliding out laterally and lacks top range. Has a history of shoulder injuries which is a concern.
Analysis: Offering enticing size and ability for a strong side tackle, O'Callaghan has the tools to eventually start in the NFL. Must receive a clean bill of health and complete his game, yet is a solid middle-round choice.
