I say start him. He can throw more accurately, he can run, and he can extend plays, and actually make them work. Fact: It will be harder for teams to prepare for Kap, than for Alex, because he is that dual threat. My only fear is that this was a fluke performance. If it was a home game next week, definitely start Kap, but we're going into hostile territory.
The fairer thing to do is have an open competition this week, and go with whoever has the best practice. Give both guys even reps with the first team.
P.S. I hope the Saints like preparing for two QBs. You know half of their prep time will be wasted.
