I would counter with this. In the college ranks, a QB can run a shotgun spread offense, send the WR's flying down the field and run all over the place. Black or white. Marcus Mariotta. Johnny Manziel.
The pros are a different animal. That might work for a very brief window, but eventually the defenses adjust and the hits/injuries take their toll. If you're not a pocket passer, first and foremost, you don't have much of a chance longer term. Every single QB that's gone that route has flamed out in that fashion. Russell Wilson is the smartest QB that's closest to a hybrid run/pass guy that I've seen and it's because I think he does go through progressions and reads and is not a duck-and-run guy at the first sign of trouble. He also rarely takes big hits and gets down or out of bounds. But right now, he's more of the exception than the norm.
Oh, I absolutely agree with all of this. But as you say, it's not a black or white or cultural thing. It's simply the fundamental difference between the college and pro games. Black QBs tend to be better athletes, and playing against lesser athletes in college, they dominate. In the NFL, the guys on the other side of the ball are just as athletic as they are, and much bigger, stronger, faster than the kids in college. It's a huge adjustment.
If his original point was Cam was dealing with the 'adversity' of the transition from playing one way his whole life, to playing another, then I wouldn't have said anything.
Cam gets the moniker of being 'the most dangerous QB in the game'--reference to how many ways he can hurt you. But I've thought it was actually Wilson these last few years. Very fast, quick, can run, can throw on the run, makes all the reads, all the throws. Very cool under pressure, clutch, doesn't get too high or too low. He's just coming into his own as a passer. The stretch of games he put up at the end of this year was mind boggling. Can't wait to watch what happens over the next few years.
