My thoughts on the QB run:
The QB Position
After six rounds, FBG teams have 1, 2, 1, 3, 2, & 3 QBs.
After six rounds, MB teams have 1, 1, 0, 1, 2, & 1 QBs.
Obviously, 3-4 FBG teams will be grabbing a QB in the seventh round and 1-3 will be grabbing one in the eighth as well. There aren't many decent starting QBs left in the pool so guys like Bledsoe, Carr, Delhomme, Grossman, Harrington, and McCown are not going to be sitting around for very long.
Teams that miss out on this group will have to take real chances at the position. They will either grab a shaky starter like Boller, Carter, Rattay, or Maddox (hoping that guys won't see the bench), or they will be forced to spend to roster spots for one player with combos like Gannon/Collins, Warner/Manning, and Fiedler/Feeley (assuming they can select both halves). Shaky starters will often find the bench, and half a combo sits every week. These players have zero chance to help their team. Having players like this puts enormous pressure on the #1 QB to produce each and every week. Being forced to accept a 200 yard / 0 TD day can be brutal when other teams in the league have 250 yard / 2 TD days sitting on their bench. Remember, this isn't just about making your team better. It's also about hurting others.
Other Positions
The QB run started at 5.05 with Dodds taking Hasselbeck. Between that pick and pick 6.12, these non-QBs were taken:
WR - Koren Robinson (5.06), Peerless Price (6.01), Darrell Jackson (6.05), Chris Chambers (6.08), Javon Walker (6.11)
RB - Tatum Bell (6.07)
TE - none

ADP data, WRs that should be gone already (like Boston, Rogers, J. Smith, and Toomer) have been pushed done the board and are still available. WRs normally taken in round seven include Bruce, Burress, McCardell, McCareins, Porter, & Stallworth. RBs normally taken in round seven include Foster and Hearst. Finally, the rookie TE Winslow is normally a round 6 selection but is still available.
Value
The QBs that were selected during the QB run are of far greater quality than the QBs that are currently available. The same can not be said at WR, RB, or TE.
Obviously, teams that did not take QBs are the teams that missed out on value. For teams that participated in the QB run, very little non-QB value has been missed. The teams without stable QBs now must either contribute to the run or all but sacrifice the position.
