I was also really impressed with Mullens. Yes his shot was off and, as he's our only front-court player likely to average over 10 points a game, there's a lot of pressure on him to score but he found other ways to contribute. His defence has improved significantly in all areas. He scored nicely in the post on a couple of occasions, which I want to see much more of. All in all he was a productive player despite the strongest part of his game not functioning.
A worrying, and admittedly basic, look at front-court vs. back-court points (I appreciate Hendo playing about 1/3 of his time at SF skews this):
Front-Court Players = MKG, Williams, Mullens, Thomas, Haywood & Biyombo.
Back-Court Players = Walker, Sessions, Henderson & Gordon.
Total Front-Court Points: 21
Total Back-Court Points: 69
Average Front-Court Player Points per 36 = 5.9
Average Back-Court Player Points per 36 = 22.2
