Before the Saban debacle, I did not feel as if the Dolphins should draft a QB in the 1st round. However, with a new coach coming in, I think it is the perfect time to draft a QB if the right one is available. You've got Daunte coming back - he should be healthy enough to play. If he does great, the 1st round QB sits for a year or two as Rivers did and you trade Culpepper after that time. If Culpepper struggles, let the new QB play a few games into the season as happened with V. Young, Leinart, and Cutler this year. The only thing that goes against this strategy is Huizenga's comment that he wants to win sooner rather than later. But I don't think the Titans, Cards, and Broncos would argue you have to delay winning by 2-3 years by drafting a 1st round QB.
I think there are 3 QBs that would be worthy of the 9th pick - Quinn, Russell, or Brohm. I think Quinn and Russell (assuming he declares) would be gone by the 9th pick. I would hope Brohm (if he declares and based on some comments made after the Orange Bowl, he seems to be considering it) makes it to #9 and is the Dolphins pick. I like his makeup and he seems to have both the physical skills and intangibles to be successful.
In looking at the 8 teams drafting before the Dolphins, obviously the Raiders and Lions will probably be looking at QB. However, an argument could be made that the next 6 teams (Browns, Bucs, Cards, Redskins, Vikings, Texans) will not be looking for a QB in the 1st round.
(1) The Browns could go QB, but they've got 2 young QBs and from what I've seen they may be looking to bring in a veteran.
(2) The Bucs just resigned Chris Simms
(3) Cards - Leinart
(4) Redskins - Campbell
(5) Vikings - Spent a 2nd round pick last year on Tavaris Jackson - they could go QB, but hopefully not. (I realize the Dolphins spent a 2nd round pick on Culpepper, but I think the situations are different.)
(6) Texans - Spent a lot of money on David Carr last year and he did progress some this year with Gary Kubiak
So, it is possible Brohm is there with the 9th pick. Also, the teams picking immediately behind the Dolphins (Falcons, 49ers, Bills, Rams) would not be drafting QB in the 1st round and therefore it is unlikely they would trade up in front of the Dolphins to acquire a QB. Panthers at #14 could possibly be looking at QB, but they would have to give up a lot to go from #14 to #8 or higher.
The Dolphins need to get their own QB that hopefully can be theirs for 10-12 years. It is the most important piece of the football team and once a team gets that position settled, it is much easier to fill in the remaining spots. The Dolphins had very low rated QBs in passer rating the last 2 years (29th in 2006 and 28th in 2005) - need to get that in the top half of the league in order to be competitive. Teams strike gold with later round QBs at times, but the most proven way to get a quality QB is to draft one in the 1st round.
