If Big Matt was running a 5 second 40 carrying that baby fat , now that he's a physical beast I would put him in a foot race with Lamar Jackson.How do you know that he will never be good on defense? Nick Saban disagrees with you by the way. Elam has good athleticism for a NG but as an OT he would probably be a step slow laterally. He ran a 5.0 forty when he was 400 lbs and he is unusually flexible/agile for a guy his size. Matt has uncommon size and athleticism for a NG but he would probably be an average OT
