Kolb has a weak arm. At camp, Kolbs passes seemed to take forever to hit the receiver. This is why he could not pull the trigger to Fitz last year. Kolb is a **** and dunk QB better suited to the west coast offense. It was a poor idea to sign him in the first place. Classic case of trying to fit a player to a system which is all ways a bad idea. Skelton had accuracy issues, but he gets the ball down field, and he will throw to Fitz. Defenses know Kolb will not go to Fitz making more difficult for Kolb to hit the short routes.
When you have a choice between two QB's of questionable abilities, I say you go with the one who is comfortable throwing to Fitz. If we go with Kolb we may as well trade Fitz for a Wes Welker type receiver. It is a waste of Fitz' time to play with Kolb. Fitz will have Kolb webs growing on his hands.
