......Defensive backfield: Extremely smart, professional, non-knucklehead players. Many were drafted as "coach on the field types" known for their smarts instead of their athletic ability ...Wilson, Harmon, Richards, maybe even McCourtney (remember how the draftniks said he was a special teams player?).
Linebackers: Very, very professional, smart players.
Defensive line: Again, very professional non-knucklehead players.
Quarterbacks: A very smart professional backup and perhaps the smartest, most professional quarterback of all time starting.
Offensive Line: Professional and smart.
Receivers: Very smart (they have to be to work in the TB offense) and very professional, no knuckleheads.
Tight End: also very smart (Gronk learned the TB offense immediately) and professional (on the field). I would argue that Gronk has this "goofy" image (that he will doubtlessly make tons of money from), but he is not a knucklehead, he is a true pro, he is just smart about developing his "brand" (I bet he will be making loads of money after his football career is over).
Running Back: The only exception to the rule. One rookie knucklehead who let Sports Illustrated go to his head, overslept, and sat the rest of the year.
EDIT: Now Released. Another obvious knucklehead who was not retained by the Patriots, he doubled down on being a knucklehead with the Steelers and got released, and was picked up by the Patriots for a song with almost no guaranteed money.
That is only two knuckleheads, and both could be released at any time (would anyone be surprised if either was released at some point this year?). Think of all of the other knucklehead candidates that have been released lately: Spikes (gone), Dennard (gone).
I think that BB has decided that at age 63, with six rings, he is going to coach players he actually likes and respects, smart, players. I think BB has made the Patriots (with rare exceptions) a Non-KnuckleHead Zone (except for perhaps the owner, but that is for another day).
Please feel free to flame away.
