Just to play Devil's advocate, I think Kolb needs another game to determine who is No. 1 and who is No. 2. He's only played one game. And he's had SOME success, including taking the Cards to 4-0.
And he was injured. Also, frankly, Kolb has gotten the **** kicked out of him from playing behind HORRIBLE lines in Philly and Arizona. The happy feet might be mental from that, although obviously he will have to correct it ASAP. Manuel does not have that baggage.
Just a note. I also think Ej will be starting, deservingly, the first week he is healthy, which I hope is Week 1.
