Well Biz minutes have been up and down, some dnp's. Ayton has been injured/sick now. So i'm not sure how much i buy into those stats right now, also Dario is looking like old Dario and moving very well now. The full court finish he made the other game, and he even got by his man last night and tried to dunk.
About Biyombo's increasingly reliable performance. That's great, but I note more that it makes his teammates look good. How? Because it means that when they're on, they can comfortably start a center who is supposedly a reserve.
And it has been pointed out that Biyombo suffers from chronic knee problems. Well, he just isn't playing like he does. Or, he plays like someone who can at times overcome his physical limitations.
I'm not going to say Biyombo is "better" than Ayton (um, no), but that I trust Biyombo to play his best more than I trust Ayton to.
