I think it's telling that it's the one area of his teams that he spent years deliberately using veterans for, rather than building up through drafting. If I had to guess, I'd say that he definitely prefers veterans, but can't find them in the sort of numbers he used to be able to, because teams became better at managing the cap, and then the cap exploded and it became even easier for teams to hold on to the Vrabels and Colvins of the world.
The good news is that he may be 3/4 of the way towards fixing the starting LB corps, with Mayo/Spikes/Cunningham, although Spikes may always be a problem against the pass.
It also tells a lot more than that DI.
1.Until more colleges start using a 2 gap 3-4 there are always going to be problems projecting how rookies will adapt to the defense we use here.
2. The number of DE/OLB busts over the last few years from the early rounds is enormous. IIRC someone posted a study where there were over 40 DE's from the first 2 rounds. IIRC the study went back 4-5 years looking at guys considered to be pass rushers. Of those 40 odd picks Only 6 had double digit sacks last season, and only 11 had EVER had a double digit sack season, and only about 5 or so had ever done it more than 1 year.
Those are HORRIBLE numbers when you consider the risk factors, and THEN add on the difficulties of learning this particular defense and its myriad of responsibilities to the general difficulties of getting to the passer
3. Even the best pass rushers in Pats history (in the BB era) have had minimal success. Willie McGinest NEVER had a double digit sack season, and only came close ONCE. Vrabel had just ONE (07) and only came close ONE other time. (03). And these are the guys everyone of us who dream of getting a pass rusher hope to find.
4. In an era where 40-50 team sacks is going to get you into the top 5 of the eague, (46 led the league last season - Pats had 34) Having a single individual responsible for over 25% of them just isn't going to happen with THIS defensive philosophy
5. The learning curve to become the kind of OLB that BB covets is a LONG one. Vrabel served a 3 year apprenticeship. Bruschi closer to 5 years. The very fact that Cunningham came right out of the box and had a ton of productive snaps last season was pretty remarkable. That he wasn't horrible and got some consistent pressure on the QB is even more remarkable. He is AT LEAST 2 seasons from becoming a finished product.
6. And on the difficulty of the getting a good FA OLB, you are right it is a lot tougher, but I think you missed the main reason. When the Pats picked up Vrabel in 2001 they were one of 3 teams in the league that used a base 3-4. Entering this season more than HALF the teams in the league will be using a base 3-4. More people chasing the same kind of players, makes it a lot harder to get one.
BTW- the same goes for the draft. A lot more competition for that "tweener" these days
And to repeat, even if he BECOMES the next Vrabel or McGinest he will RARELY, if ever, become the kind of sack guy that people here dream of.
So finally, when BB is trying to decide between a potential great pass rushing threat (whose position bust rate is around 80%) and a potential franchise LT (whose position bust rate is around 10%) who is he going to choose. Or rather who SHOULD he choose.
I wrote a post were I opined that the BEST sack artists in the league have about a 3% success rate. I'm guessing that BB feels better about a getting a tackle who could have a positive impact on over 90% of the snaps he sees, vs a pass rusher who will have a positive effect on about 10%......and that's on a good day.
So getting back to the original point...at last. The chances of the Pats find ing that pass rushing gem we all want is much greater if we get him out of the vet FA pool, rather than from the draft. And as we have seen, even THEN, the odds are small that you will hit gold.
I believe that BB actually doesn't care if he finds a great individual pass rusher. I think he focuses MUCH MORE on how he can get more sacks/QB pressure from the ENTIRE TEAM.
Great individual sackers can be neutralized too many ways. No team in the league over the last decade has put more pressure on the QB consistently and well than the Steelers. And how well has THAT worked out for them when they play the Pats. Even in the few games the Pats have lost in that time period, the Steeler rusher WAS NOT the determining factor.
After the initial outrage, the more I have thought about the more I have come to the conclusion that your draft assets are much better spent on other positions other than on a pass rusher. That doesn't mean NEVER, just the great majority of the time. BB has spent exactly one pick as high as a second (Cunningham) and....so far so good.
