Let's not forget Shump received DPOY votes as a perimeter defending rookie and also was on the All-Rookie 1st Team and seemed to finally be getting his rookie bounce back at the end of last season. George also took his game to an MVP level only this season, but last season he averaged 17pts, 8reb, 4ast as a great 2-way player. It looks silly now, but it wasn't too far-fetch'd to say that Shump could have become an SG version of that by the end of the 2014-15 season.
Dude looks lost now though. You can't play a role on offense without doing anything well. Dude needs to get good at something already.
It's obvious that injuries stunted his growth, but imo a newly found social media fame and coolness here in NYC compounded that. Dude admitted his focus wasn't locked into basketball (which imo meant rapping, his image, and yambs.)
