Without seeing much of the improved Mahinmi yet...
I'm going to continue to say that's he's going to be a very good player. He's got work ethic(he does what the Spurs ask him to do), he hustles, and he's got tremendous athleticism...
He's also got one of the most skilled bigmen to ever play the game to help him develop his skills...and he's got a young countryman, who's developed in a similar manner to push him and encourage him to do it...
No...Ian's going to be a successful player IMO, it'll be next to impossible for him to fail, as long as he stays healthy. He wants to be good, he's willing to work to become better...and he's got the talent. That's what it takes...
