He's been and will be better, but how does that translate to winning is the key question. The evidence suggests that the current starting lineup struggles... they may not be offensive struggles... might be defensive issues, but it makes sense to me... you have DM, Mike, Joe who all play with the ball in their hand... Bojan who can play with the ball in his hands a little and Rudy who is low usage but highly efficient. Throw one too many cooks into the kitchen and now Rudy isn't seeing the ball enough or the other ball handlers are under utilized. The Wage Lebron thing made sense to me because neither guy was a great shooter at that point. Our guys are good shooters so they should be better, but they are small with that lineup and they don't get a lot of rebounds/loose balls.
So when you take a super duper low usage guy like Royce, who provides some of the things that lineup needs (defense, length on the wing, rebounding) and replace it with a high usage player that isn't as efficient as your other high usage players then it throws things out of balance. There are ways to limit the starting lineups minutes together, but when you start them you are avoiding you best configuration and using one of your worst configurations... all in hopes that the bad configuration could someday be as good as the already best configuration. Its like me investing $10,000 in a somewhat risky investment that will hopefully someday pay me $10,000.
Run it out for another 5-10 games to get a larger sample, but at some point just trust the ****ing data you have and adjust.
