My question is, how many QBs at his height have been tried in the NFL. Or has this height barrier kept them from trying?
Kyler is a special athlete. He has an arm and his body motion generates tons of torque for his size. He can easily throw the ball 60 yards in the air with pin point accuracy, from the pocket or on the run. A lot of his throws are roll outs where his height doesn't matter. If he can get a line that opens throwing lanes, like Brees' does he can be a force. Add that he has insane speed and he can hit that top speed so quick, you add another facet to your offense.
He might do nothing. He might get killed and be the next RG3, but there is a potential here... And for some teams that have been wallowing at the bottom for years, they need a spark. Kyler can give it and give it day one.
