This team is obviously a great team, with some flaws. BB has done a very good job of getting younger while still maintaining that championship caliber.
The biggest plusses-
Best QB ever in Brady
A deadly TE combo
A very good LB corps
A versatile D line with Wilfork, Jones and Nink
An up and coming secondary if they re-sign Talib
The Big question marks-
Health is obviously a big one. BB uses little white skill players better than anyone else out there, but small stature doesn't lend itself to durability all that well.
On top of that, Gronk's style of play also opens him up to injury as we've seen the last 2 seasons and his time at Arizona.
The secondary, while markedly better, still needs strengthening. I think Talib/Dennard could be a terrific top 2 at the corners, and Arrington is a fairly solid nickle. McCourty has shown he's a good safety, but they need another solid safety, and a whole lot more depth. The framework is finally there, but it still needs improvment. I was really thinking Ed Reed might be worth throwing money at (without hamstringing them financially), but Brady's Cobb slide yesterday might have re-invigorated that bad blood. I hope I'm wrong, because he would be a great addition.
I love the aggressiveness and size of Mayo, Hightower and Spikes, but they may just be too slow in pass coverage. They're great against the run, but the short passing game is what killed the Pats yesterday. Baltimore was always able to pick up that short 1st down pass. If this is the group BB wants, then the pass rush and scheme needs to cover it up.
Welker, while great and worth keeping, just isn't clutch when he needs to be. Last year was a bad pass, but there were quite a few yesterday that he simply dropped. That can't happen.
So, as far as improving, I think they take that shot at Reed, and they draft for d-line help and more secondary depth, and they need to get a big play reciever...I'd say tall speed over big bulky red zone guy...but I think a little height is needed with the shorter wideouts they have now.
I dunno, I think this is all fairly attainable, how about you?
