Top 3 places for Kolb, IMO: Miami, TN, SanFran, Arizona.
I know both the 49ers and the Cardinals have been discussed here a bit, but neither of those teams had and O-line as comparable as the Dolphins. I think Kolb has to take that into consideration.
We all know the Young issue in TN, and Chris Simms or Collins cannot be their answer. I know that the Titan's main focus must be on finding the right HC right now, but I think Kolb would be a great fit here. Best RB in the league, one of the more talented young WRs in Britt, and a pretty solid D.
I think the best fit though, would have to be the Dolphins. Good running game with an even better O-line. Great #1 WR with a good complementing cast, and a TE with solid hands. And a D that keeps this team in games against some tough AFC opponents.
