He has outplayed him in the pocket, no doubt. JB is a more prototypical pocket passer, but the OL will eventually get him killed and hes been terrible under pressure in 2 games. Kyler does other things that JB can't do.
If you want wins this year, stats show you go with Kyler, if you want 300 yards in the air and a 1 or 2 wins, then go with JB. I'm a fan of the latter for the draft since this team isn't a SB team or playoff team. JB has won a single football game in the last 3 years and 5 games in the last 4 year. He is 5-15 in that time.
