I know JR has been playing great in the starting lineup, but when you look at the roster moving forward, Shumpert starting and JR off the bench makes sense. We have offensive spark off the bench right now. Even with Andy coming back, neither him, Delly, Tristan or Shump are instant offense guys. JR however will get shots up no matter the amount of minutes he is given and will sometimes make a ton of them. Shump, from what we have seen this series, is a rhythm guy on offense. He'll take what comes to him and make the most of it. Watching him come off the bench this season, you would often see him force stuff because he knew he was the best option to generate offense, but it just didn't work. Playing with Irving and James (hopefully Love next season) he suddenly is amazing at taking the open shot, cutting when the lanes open up, and just being active without the ball.
With that adjustment and just bringing everyone back this summer would give us a complete roster.
