lin will win it (having played like 36 games), pekovic should get it (dude has been a straight beast, though he got injured as well), and mully certainly deserves consideration, he was putting up video game stats the last 2 games. i'm glad for all these guys though and i hope mully keeps improving.
I'm not huge on the Lin hype but I do think he could arguably be deserving. The guy went from not being in the league to starting at PG for the Knicks. Pekovic certainly deserves the title as well, where he went from a relatively unknown to a viable option on that team. Byron has had a great season but he really doesn't stand a chance to win MIP (which takes absolutely nothing away from what he has done).
