Hans and Currry have their supporters, but to me, it's a one man race. Blake Griffin has been the best player this season, to date.
Not many have noticed, as the powers that be at ESPN tend to ignore basketball west of oh, Chicago. Maybe they get to Kansas. But OU isn't discussed much.
My opinion is that Griffin is the Player of the Year and it's not particularly close right now. Curry is amazing, but he's not the contributor on both ends that Griffin is. Hans is not the most valuable player on his own team (that's Lawson). Most outstanding, maybe, but not most valuable.
Just my opinions.
