Honestly, AB gets so much hate on these forums and I really think he deserves a bit of slack.
If you look at this team over the past two seasons (since KG and Doc left):
1) Avery Bradley has been the Celtics' undisputed defensive leader. Not only does he frequently accept responsibility of defending the opponents top perimeter scorer, but our lack of a legit rim protector means he is essentially the Celtics first and last line of defense (quite literally).
2) He has been forced into the role of a top 3 scorer for the past two seasons (something that isn't a natural role for him), and had to take on a far greater offensive load then he's ever had in the past. No longer can he score quietly in the shadows while the stars do the heavy lifting - now he is doing the heavy lifting, and the defenses' attention is all on him.
3) He is one of only three Celtics players (the other's being Rondo and Green, who are now gone) who averaged over 30 MPG over both of the past two seasons. So not only has he got far greater responsibility than anybody else on the team, he's also playing more minutes.
4) He's had to make the mental transition from Padawan to Master - going from the comfort of being able to sit back and learn from a bunch of hall of famers, to being forced to take charge and become a leader of a group of guys even less experienced than he is.
There is honestly no player on this Celtics roster who has had to deal with more pressure over the past two seasons (both physical and mental) than Bradley has, so it's only reasonable to expect that a number of aspects of his game are probably going to drop off as a result. In this case it's been primarily his defensive intensity and his tendency to attack the basket. Both are understandable given the amount of physical energy he's had to expend on both ends of the court the past couple of years, as well as the mental energy of all the extra responsibility on his shoulders.
This year Bradley is going to have some help all year long. He's got Thomas and Lee to help take off a lot of the offensive load, and Smart and Johnson to help take off some of the defensive load. He also now has other vets on the team (namely Lee and Johnson) to help lead the team emotionally.
All of this should take a LOT of pressure off Bradley, so I'll be to see if his defense and his offensive efficiency start to improve again, and get closer to where they were in 2011/12.
Either way I applaud Bradley because he has never come across to me as a natural born leader (or a natural star talent) yet he has taken on so much load and responsibility these past two years, and I've never once heard him complain about it. He never complains about pressure, about role, about responsibility - he just goes out there and does whatever the coach asks him to do.
I seriously don't get how anybody could criticize this kid - if you look up the term "team player" in the dictionary, there should be a photo of Avery Bradley smiling back at you.
In fact I'm going to go out on a limb and say that there has probably never been a better "team guy" in a Celtics uniform than Avery Bradley. On par maybe, but not better. He works his tail off every single night, plays every possession like it's his last, and does everything he's asked to without question or complaint.
