It's crazy how intense this has gotten.
EJ Pro: Can get out of pressure situations better, and protects the ball better.
EJ Con: Doesn't take many chances, less accurate, and doesn't read the defense quite as well.
KO Pro: More accurate, ball comes out faster, throws are harder, reads defenses better. Willing to stand in the pocket to make a throw.
KO Con: Doesn't protect the ball very well when under pressure. Throws bad interceptions sometimes.
I'll take KO for now, assuming he can get back into things and protect the ball better. But, EJ may very well grow his game over the next few seasons, so I see no reason to give up on him yet.
