So your rationale for drafting VY is that the team is in full rebuilding mode. That makes sense if you belive that, but I, as well as most other trade down/D'Brick guys, belive that the team isn't all that far from success.
We are going through a major transition, with a new coaching regime and new schemes and philosophies on both sides of the ball, but from a talent standpoint the team underachieved this past season. Just in '04 the team went 7-9, and most of us were shouting playoffs in '05. Capers & Co. tried to implement a system to reduce the sacks on offense, and for a while it worked (well actually, just the Bengals game), but it quickly proved an ineffective system, and coupled with Caper's/Pendry's conservative philosophies, the offense had trouble functioning. Worst of all, Carr's sack numbers went UP from '04.
Capers then ejected Sharper and Glenn in favor of younger, faster, more athletic guys. It sounded great at the time, and Sharper and Glenn were in the down of their careers, but the new guys (Buchanon & Greenwood) disappointed. Greenwood wasn't big or physical enough for the 3-4, and P-Buch couldn't handle the complex zone scheme and the lack of safety support from Coleman.
Kubiak is good at tailoring his scheme to his talent (tosses for Terrell Davis, cut running for Portis, play-action and bootlegs for Plummer) and is capable of bringing out the best on the offense, and his assistants on D will likely do the same. With upgrades at several postions, we could explode this coming season.
Oh and, D'Brick is being talked about as a rare type of talent, one who wasn't available last year or next year. We have an opportunity to address one of our actual needs with an elite prospect, rather than succumbing to flash and fluff.
