He should get the nod because he's having a historic season in addition to being one of the catalysts for the best team in basketball
The reason I say Korver is benefiting from having better teammates and a better coach is put it like this, if Korver had the exact same stats he has now but the Hawks were 29-23 like the Bucks are would he even be getting any serious consideration for the ASG? Odds are not at all.
