Its o.k. to defend Woody where he deserves defending. And Kelel and Mack's improvement call for that, in my opinion.
Malik, however, I don't think has improved much. His footwork and positioning defensively are still really bad. He isn't really any better passing out of double teams than he was when he arrived in Bloomington. I don't think he's expanded his game all that much.
He improved his body, which helped his stamina, which probably helped his production. But I think the main thing that led to his increased points, rebounds, etc... was just that TJD and Race were out of the way.
My only concern with Malik possibly transferring out is that maybe he isn't responding to Woody's program, and realizes that, and knows with his size and skill, his future in the NBA will rely on him expanding his game out further from the basket...and maybe he knows like we do, that Woody isn't the guy to help him with that.
Also, his body language got worse and worse as the year wore on. And his overall game devolved the last month or so. When others seemed to galvanize, and start pulling in the right direction. Malik fell apart. Didn't seem like he was on the same page as the rest of the core guys.
