You couldn't be more wrong. Yikes.
I think the small sample so far of Mikey missing shots is too soon to judge. He made some pretty good progress on his shooting (both 3's and FT's) in HS. He's not as bad a shooter as his early HS would suggest or even early college.
I don't think he's gonna be a knock down shooter but he can fill the 2-3 per game attempts from three kind of role eventually. He should be a pace pusher and distributor mainly. I would guess he will eventually (not this year) be in the low 30's in % from 3 and hopefully above 75% or so from the stripe.
