I can understand that. And I've been a detractor as well. But I have to admit, he scrambles around and makes plays that way pretty nicely. He's also been uncanny accurate this year. Both of those are premium tools to have in the tool box when he jumps to the pros. The more tools you have in the tool box, the ones you can rely on when plays aren't developing ideally, the more likely you are to survive until you really start to figure things out and develop command of the way NFL defenses play against your offense.
I've been softening on him. I liken him to Russell Wilson coming out of Wisconsin. For both guys, you can say that, if THIS is what the guy ends up being in the pros, then he'll be stupendous. But with both guys, there was a potentially fatal characteristic that could stand in the way of the player making that jump. For Wilson, it was his being 5'11". For Burrow, it's his total lack of an NFL level fast ball.
I said this back in 2012, this made Russell Wilson a boom-or-bust player. Either the height matters and he gets run straight out of the league (perhaps hit so hard he wakes up playing baseball, like Pat White)...or he's going to be the amazing QB he was at Wisconsin (and NC State).
The same is likely true of Joe Burrow. Either NFL defenders will start to crowd the plate on him, he won't be able to challenge them with his velocity, and the athleticism which has been such a weapon for him in college sees him ending up looking more like Ryan Fitzpatrick in the pros...or he'll find the right offensive system, and the short passing game that has become so prevalent in the NFL nowadays will allow for him to be the quarterback he is, another potential Drew Brees or Tom Brady. I don't see a ton of in-between.
