Pros: O’Callaghan combines enormous size with good agility and a massive wingspan. Over his final season he played through a broken wrist. When he gets his big mitts on a defender, he is difficult for most to shed. He is a quick study and has made line calls. He has fine functional strength to go with his imposing size. He can sit and anchor against the bull rush. He does get set up fairly quickly for his size, and is able to make blocks on the move when he reaches the second level. He is also a prospect on the inside and could be a big Kevin Gogan-type of guard too, though not useful for teams that pull regularly. He can pick up a blitz or stunt and works well switching off, showing enough agility to quickly move to either side.
Cons: He had multiple surgeries on his left shoulder, but he has not missed any time due to that injury. He is not sudden or explosive, and his hand punch is only average. His initial pop is barely adequate at this point.
Numbers:: At the Combine he ran the 40-yard dash in 5.37 seconds with a 25” vertical jump and a 7’8” broad jump. He did 21 reps of the 225-pound bench press.
Skinny: He is similar to tackles Todd Wade and Adam Meadows, who have played almost exclusively on the right. He has the talent to start in the NFL with some development. He could fall through the cracks in this deep class and be on the board late on the first day or early on the second day. He is a top 100 prospect in which teams like the Jets, Titans and Browns are interested.
