See post #30 in this thread above, where I detail our picks and signings since 2003.
Pittsburgh has drafted (or signed as UDFA) more LBs than the Pats since 2001, no doubt about it. The Pats have signed more FAs, some good (Vrabel, Colvin, Thomas and Seau) and some not so great (Brown, Beisel, Hobson). Pittsburgh's only major FA signing was Farrior, who has been terrific for them.
I am being fair, I think. I said in my earlier post (#30) that I thought BB had just missed on some good players (Tatupu, Bradley) but had also made some possible mistakes in passing up on others (Dansby being the most obvious; it's too early to tell how the players he passed up in the most recent draft will turn out). We have been far from perfect in the LB arena, and I think BB's biggest justifiable criticism is that he waited a bit too long before rebuilding the position; but he has made some efforts, and we have had some unfortunate injuries and unexpected events (the timing of Johnson's retirement, Bruschi's stroke). Pittsburgh has been far from perfect too, but has a bit more to show for their efforts, mainly because of striking gold with Harrison. Woodley has developed beautifully so far. Farrior is aging, I'm not convinced Timmons will be more than solid, and they have little depth at ILB. They clearly deserve a lot of credit for knowing what players fit well within their system, and I think **** LeBeau deserves enormous credit.
I think BB got caught by being a bit too loyal to his veterans and dragged his heels a bit in terms of rebuilding the LB corps. As a result, age, injuries and lack of speed caught up with us in 2006-2007. But he invested a lot of resources in the position in the last few years: Thomas, Mayo, Woods, Crable, Redd and Guyton all have 2 or less seasons of experience behind them (Woods was drafted in 2006 but played exclusively on ST his first year). Again, I was hoping for a day 1 LB this year or a major trade/FA signing; but if BB thinks those guys are developing and is willing to go with them, then I say we need to give them a chance.
