Regarding using a 4th round pick for him, I didn't notice anyone mention that we don't have a 5th or 6th next year (due to Ocho and Haynesworth).
So it isn't exactly true to say that BB thought he was '"worth more than a 5th of 6th round pick" because he didn't have that option.
I would assume that BB offered a 7th round initially and Tampa held out for more. The next highest offer we could make was a 4th.
So I'm not sure that one can read too much into the use of a 4th round in this case.
Is this a "desperate" move?
Yes and no.
Do the Pats have a serious need for better talent at DB?
I think we all agree the answer is yes.
Does Talib have talent?
Yes, but as it was mentioned before, we have to see him play in our system to know if he really can help.
I like the move since it reflects the fact that BB is doing something and trying to make the team better.
I'm not worried about Talib being a problem in the locker room. I think Brady, Vince, Mayo, etc. will be able to 'splain to him just how things work there.
To put the draft pick cost in perspective, for a proven, accomplished starting NFL CB, BB just spent the same as he did for Wilhite back in 2008 (very late 4th-rounder).
