All right, time for the bad ones.
Least Valuable Player (s)
I think J.R. Smith was the biggest let-down. Winning the 6th Man of the Year award last year was a big ego boost to him and made him think he could do anything he wanted to do on and off the court. His stats decreased in almost every category this year.
Evan Turner (2nd half)
Evan Turner was averaging 17.4 points 6 rebounds and 3.7 assists, which are career highs in every category. What's so bad you may ask? At the trade deadline, the Pacers traded for him. Since the trade, Turner is averaging 6.8 points, 3 rebounds, and 2.2 assists while dipping from 43% to 39% field goal percentage and a 12.39 PER.
The first overall pick in the 2013 NBA Draft... And for what? Of course no one expected it *insert Bill Simmons' "WHAAAT" on national television*. Well people should agree with him. 4.1 points and 2.9 rebounds? And on top of that, he missed his first 15 professional shots.
Least Improved Player
I'll take contract extensions/signings into play here
Josh Smith was signed by the Pistons to a four year $54 million deal. Right now, that deal doesn't look very good right now. Smith is averaging career lows in every category since his rookie year. Most of this blame can be put on the Pistons coaching staff because they wouldn't let Smith play his preferred power forward position. Instead, they insisted on starting all three bigs, in Drummond, Monroe, and Smith.
Andre Iguodala signed with the Warriors for a four year $48 million deal. Like Smith, he's put up career lows in everything since his rookie year, except he has no excuse. The Warriors presumably had excellent talent, but they are only the 6th seed. Coach Mark Jackson just may be on the hot seat.
O.J. Mayo was signed to a three year $24 million deal by the Bucks. So far, he has career lows in everything for this excuse of a NBA team. You know what they should do? Every team with below 25 wins has to play the NCAA champion, and if they lose, they can't get a lottery pick.
Not Coach of the Year
Mike Woodson. It could be his fault to be in the state that they are-Bargnani over Stoudemire-after the year they had last year. They kept almost the same roster, but they are still a below 40 win team.
