There's been much discussion whether a move should be made back to EJ? There's also the larger question of the Bills' future at the QB position.
The great NFL QB's (e.g Manning, Brady) have the courage to stay in the pocket, go through their progressions, and take a hit. In the case of the smaller stars (e.g Russell Wilson, Drew Brees), they have great athleticism, awareness, and a fast release.
Most agree K.O may not be the Bills long term answer but seems to have toughness. Assuming 'you can't teach guts', does EJ have the right stuff?
