I think Pop is trying to expand Danny's game and make him less one dimensional on offense. It's a noble experiment, but it just might not work. There are players like Kawhi, Steph Curry, Steve Nash, Draymond Green, etc., who can build on their games and be much different & better players in, say, Year 5 than they were in Year one or two... Bruce Bowen was a valuable player, but he was never able to expand his ballhandling & passing skills to the point where he could be dangerous in that regard. I thought two years ago that improved ballhandling skill for Mills, Kawhi, & Green was an important goal for the Spurs as Manu & Tony aged, so 2 outta 3 ain't bad.
On this same topic, one of my favorite non-Spur players to watch this year is Nick Batum with Charlotte... he's having a good year, more like Manu than Green, with great assist/rebound numbers and a respectable 37% from three. He's a free agent at the end of this season, and has lots of connections to the Spurs-- friends with Boris & Tony from the French National team, and former teammates with Aldridge & Mills... His D reminds me of Aldridge's in many ways-- he doesn't look like he's playing in an especially aggressive way, but definitely has the ability to be part of a great defensive team.
