I'd consider Exum a project pick. The Jazz can ease him in with 15 MPG and gradually build his confidence and strength.
I still remember everyone saying that Delly would never get an NBA contract and that Patty would get dropped. Haters still hating.
You remember
some people making either negative comments or qualified criticism. All players are going to have their backers and their critics. In many cases on here, someone offering qualified criticism is instantly labelled a hater and it's ridiculous.
I can see Exum being a spark off the bench this World Cup. Where he was picked and what his future holds are largely irrelevant to much beyond blooding him and they don't need to start him for that.
I think OP is a bit off with his 12th man comment though, especially now that Mills is out. With Mills, I think that backcourt is a bit crowded with Mills, Delly and Ingles being pretty obvious picks and then guys like D Martin, Goulding and Gibson are either tough or fiery which always helps. Was Markovic named to the Boomers squad?
