That's not easy to answer. He probably can make every throw, I think every QB on an NFL roster can make every throw, but the weaker the arm strength the harder it is and the more open the receiver has to be. And I know I keep bringing up the hand size thing, but I think it's a huge deal that kind of goes under the radar. Russell Wilson and Drew Brees have larger hands than Matthew Stafford, Matt Ryan, Cam Newton, and Carson Wentz. In other words, those two are kind of physical freaks. I don't know, maybe KM does too, but I highly doubt it just by his build. Everything about him looks short and tiny.
He mostly operates in wide open spaces in college so that isn't nearly as important. It's just a different ballgame in the NFL. I get a kick out of Kiper supposedly saying he's the best dual-threat QB prospect he's ever seen. Well, there is no such thing as a dual threat NFL QB, with some small apologies to 250 lb Cam Newton. 240 lb LBs that run 4.5 fortys and $25M contracts will do that.
