I don't know if you can disagree with those 2 concrete stats. (3-4 record as a starter and 11-14 TD to INT ratio) (sarcasm)
Ok, look at Kolbs 4 losses: New Orleans, Packers where he got hit and knocked out of the game, Titans (see Kenny Britt) and Cowboys (last regular season game where 0 starters played for the eagles). Look at his passing stats. That 11-14 TD to INT ratio is a cherry picked stat. He's still only started 7 games, so that stat is actually pretty good, and at least 3 INTs were on hail marry's.
He goes on to say Kolb is a worse choice for the Cardinals than Bulger, Palmer, Hasselback, and Vince Young. I guess he really likes injured quarterbacks... and Vince Young.
