Reminds me a bit of Cam Newton, who's built like an absolute tank. The coaching staff in Carolina should have done more to protect Cam over the years. He's a pretty good pocket passer - not an exceptional one, but certainly hovering around top-10 in the NFL when healthy. But he was special because he could break from the pocket, and unlike Wilson, Cam invited and even sought contact because he was so big that he could bully most linebackers and defensive backs. The problem is this exposed his lower body to all sorts of injuries, which in turn has begun to limit his ability as a passer as he moves into his 30s. People dismiss running quarterbacks, but the issue is less with running quarterbacks' skills than with their longevity. It's one thing if you're playing 10 games a year for 3 years in college... when it's 16+ for a decade in the NFL, with bigger and faster guys coming at you, well...
For what it's worth, I think Jackson could make a successful transition to a Wilson-type. But I think the Ravens are going to have to alter their offense from what it is now to get him there. Otherwise they risk bottling a shooting star for a couple years but losing it down the road. Maybe there's something to that - riding a QB to death for their first rookie contract then discarding him for another new, shiny QB.
