The Pats should not waste their energy scouting anybody in, say, the top eight. If any one of the top eight falls to about #19 without a drug bust or something, BB will jump up and grab them as it's a no-brainer, but it's not going to happen. One of the #9 through #20 players has a legitimate chance of falling to around #19 or #22, and those might or might not have legitimate reasons for BB to pass on them too. BB considered Vince Wilfork to be a top 15 guy who dropped to #21, and grabbed him.
No, BB will not jump up very much for anyone. The Patriot strategic plan is to go in the other direction, where the profit lies.
