If Jacobsen and TKR are starting and Burgess is playing big minutes (at least some of which will be at the 4) I'm confused as to why you think that means that Heide is playing most of his time at the 4 as well. It's not what we saw before Jacobsen went down.I know it COULD happen, but I’m pretty sure RB is not going to RS next year. He has all the tools to be great for us. The game is a bit fast right now, but with this season plus the offseason with Paint and staff training him, along with gaining 15-25 lbs of muscle, he should be easily ready to produce at the 10-15 min if not more. Him and DJ in two years at the 4 and 5 will be tough for any team to go against.
If Heide isn’t playing the 4, I’m not sure what the mins breakdown would be at the 3 between Harris, Heide and Colvin and even Cox too.
The only reason we are seeing it now is because Berg and Burgess aren't ready to play a lot of minutes. If they were, he would be playing a lot of 3.
