If Cam gets a couple touches I won't be upset. He is not as electric as some of the other guys, but he can play. Anyone who has seen his highlight video can attest to the fact that he is good with the ball in his hands. I wouldn't mind seeing him get used a little in the passing game out of the slot - as all players at the position are cross-trained to do.
Cam is 5'10"/195 without breakaway speed, but he has excellent body control and shiftiness. He was way under-recruited despite being a dominant player at a Texas high school football power because of his size (and honestly, probably his pigment).
Wes Welker is 5'9" 185 without breakaway speed, but he has other-wordly body control. It allows him to run super-precise routes and consistently beat the first would-be tackler. Wes was way under-recruited despite being a dominant player at an Oklahoma high school football power because of his size (and honestly, probably because of his pigment).
I'm obviously not saying Cam will definitely be the next Welker. He isn't the first 5'10"/190 shifty white guy who was good in high school to come around since Welker came out in 2000. Plus, Welker's pass-catching skills (despite the Super Bowl drop) are insane, and his ability to "think football" is also off the charts. We don't really have any idea where Cam is at as a pass catcher or as a football thinker. He looked like a decent receiver in his highlight video, but obviously highlight videos don't feature drops.
All in all, I definitely won't be upset if/when I see Cam in the huddle over the first couple weeks of the season.
