Martz and Harrington are a pretty good marriage. Harrington is a very cerebral, smart quarterback and Martz will help him translate his smarts onto the field. They paid up to get Martz IMO so that they don't have to take Cutler. So, I agree with you there.
However, that's not the main outcome of this move. The main outcome of this move is that they WILL NOT select Vince Young. Never in a million years now.
IMO, the Lions will never get the chance to take Cutler. I think Tennessee will take Cutler at #3...possibly even the Saints at #2. If Tennessee has a choice between Leinart and Young, they take Leinart cuz of Chow. I firmly believe that. If they have a choice between Cutler and Young, they take Jay Cutler or they trade down to get out of the pick. I firmly believe that as well. Vince Young just DOES NOT fit Norm Chow's offense. It's like chocalate ice cream and onions. It's actually pretty lucky for the Titans that nobody is really talking about that...cuz it makes a trade down possible.
The question to me now becomes will the Jets pass on Young at #4, and will the Cardinals pass on him at #9, because there's no way Young will end up a Detroit Lion with Mike Martz signed to a $1.5 mil/year deal as OC. I think the Jets take Ferguson over Young. I think the Cardinals take LenDale in Glendale before Young, because Vince doesn't fit Denny Green's vertical passing game. Green does not favor running QBs, because they minimize the stable of talent in the WR group, and he's accumulate a pretty nice stable of talent in Larry Fitzgerald, Anquan Boldin, and Bryant Johnson.
This move convinces me more than ever that Vince Young will be available at #16. Before I probably felt there was about a 30% chance of Young being available at #16...now I put the chances about 50%.
