It's frustrating to see Mark Jackson start Festus Ezeli, the 30th pick of the 2012 draft, and actually get some decent paint presence out of him, even though Ezeli tends to look terrible when he tries to do anything more than rebound, box out, defend, and try to block shots.
He's playing only 16 minutes a game, and has some serious holes in his game (39% FT shooter, but he gives the Warriors an answer while Bogut continues to mend.
I'm hoping Melo can come in and do this type of thing the second half of the season if Ainge can't make a roster move to bring in a big body who is a bit more uncorpselike than Jason Collins.
To be fair to Collins, he's decent as a big body who mucks it up and fouls. His role is as a 12th guy who plays in games where you need to foul the opposing center a bunch of times. Starting him is using him in a role where he doesn't have the ability for long term success.
