I wouldn't have been upset if we had taken Kindle instead of McCourty, but in retrospect, I think it was the right move. A CB of McCourty's caliber will have a much bigger IMMEDIATE mpact on the Pats D than an OLB project, regardless of the talent, is going to take time to make an impact.
Also I think you missed on the importance of getting BOTH the TEs, though I doubt BB thought he'd have the opportunity. I am among those who think that BB has decided to rework the offense philosophy this season. I think teams have started to catch up with the spread offense that has worked so well for the past 3 years. I think Gronk and Crumpler gives us the best opportunity in years to line up with 2 TEs, BOTH who are good blockers, and BOTH who have receiving skills.
2 TEs, 2 WRs and a RB is a very difficult formation to defend. Its balanced. As the DC, you really can't afford to go to a nickel or dime package. The mismatches would be 2 big, so you have to keep all your LBs in. Because the formation is balanced you can't overload one side. Any motion by a TE or WR would immediately tip of the coverage.
Here's were the drafting of Hernandez comes in to the picture. He, like Dallas Clark is a great mismatch if he lined up on a LB in athleticism, and he can out muscle a DB. He gives us a very real, but different kind of threat in the slot. Besides being a great blocking threat.
The TE had disappeared over the last few years. It can be argued that the fault was in the system, or the fault was in the TEs, but the fact remains, the TE was effectively written out of the offense. THIS will change and the unlikely opportunity to get Hernandez in the 4th made it possible.
BTW- it is my impression that there will be better impact pass rushing prospects in next year's draft than were available when the Pats were going to draft THIS year. Better that we got the secondary solidified (and I think its going to be a great one) over the last 2 years, and grab that special pass rusher next year. And who is to say that Cunningham won't be as good a prospect as Kindle. They have very similar numbers, and Cunningham doesn't come with the injury risk
