I'll be interested to see how his combine goes. It could really be true that he was hampered by the shoulder injury in 23, and the oblique in 24, and that with proper rest and better luck, he could complete accurate throws downfield. However, he sort of ran out of chances to impress in that category at Texas.
He's demonstrated good mechanics (usually), shown he can make off-platform throws, and for the most part read a defense. After this season's injury, he sort of stopped trusting his reads, would double check, and throw late. Hard to imagine getting a better OL than what he had at Texas, so he'll need to learn to climb the pocket rather than self-sack by spilling sideways.
There's a lot to like. A team that won't need a starter until 2028 or so will get a bargain.
