The thing that needs to be pointed out, and it was by Fisher himself..... Everyone is basing most of their "evaluation" of Kellen Clemens on his Preseason Performances, which is pretty much all we see.
But, IMO, he is the kind of guy, who may not always look pretty doing it, and might not be "conventional", but he always seems to find a way to make plays. He made enough plays in the Cleveland game to give us a chance to win. He stunk it up against Green Bay, for reasons not all under his control. Then he plays well, against Baltimore and wins the job.
When put in a game situation, he is, the better option.
Even Fisher recognizes:
(On how much QB Kellen Clemens helped his cause for the No. 2 quarterback spot last night against the Ravens after his performance against Green Bay)
“We take everything into consideration. His rough night in Green Bay – played a little bit later, didn’t have as great a supporting cast, and Green Bay was doing a lot of exotic pressures. He was under siege. Last night, he had protection, which he would if he’s going to be in the game with the starters. I thought he executed and did a nice job.”
The bottom line, there just aren't many GOOD backup type QBs in the league anymore. Overall, if you are any good as a QB, you are most likely STARTING.
