I've said this a few times, but Burks sitting and watching is going to pay huge dividends. Last year he played pretty well not being 100%. He's a guy, that when firing on all cylinders puts the most pressure on the defense. He's the most physically gifted wing on the Jazz. The biggest question mark for me has always been the mental aspect of the game for Burks.
As he wasn't able to play, he's put in what work that he could watching film and watching the team have success and just being able to understand Quin's offense more and how to fit in.
With that said both players are going to be very good players.
In hindsight his injury might be the best thing to happen in his career. That would be awesomely weird.
