Difference is motor. Fes doesn't have one sometimes. It's early but it looks like Bismack's motor is something to drool over.
But I like Fes. I love his size and he's funny. I'm running out of patience with him but I still think him on the floor is a good thing overall. I'd love him back for the right price.
The thing is you rarely see him bashed here for his defense. His fouling rate is concerning sometimes. But other than that the very same people who want to get rid of Fes because he is zero on offense and sub-mediocre FT shooting are all over the forum vouching for drafting Biyombo in lottery who is much worse than Fes in this component. I simply don't get that.
You don't draft Fes' replacement with 12th pick.
