OK. I have a gripe against McD. When you draft two players who play the same position in the draft, you create a situation where one or the other, or both in this case, are second-guessed and pitted against one another constantly. It has not helped either Chriss or Bender to have been drafted in the draft an on the same team.
As I've posted, I agree with you, even though some of our co-posters don't. I'll introduce a word that has not been mentioned. Confidence! It is up to the coaching staff to instill it in each young player.
Going against each other in practice is one thing. But not knowing, from game to game, which will be the starting Power Forward or for how long (which is the way it played out, not using one as a Center and one as a Forward) does not build the same confidence as "Here is your role (whatever it is) and we're going to help you achieve it."
Another word has not been mentioned in describing the coaching staff in this situation. Indecision!
It reminds me of the season when the hapless (which they were at that time) Chicago Cubs did not name a Manager. The coaching staff members alternated in the position. It was a failure! This is not a direct comparison, but the philosophy is the same. Make a damn decision (who is the starter and who is the backup), give it full support and monitor how it's working. Confidence!
When ballplayers play out of fear of making a mistake, it does not have good results. This experiment is just another example of the gimmicks the Suns have come up with during this decade. Hopefully, that will be behind them with one claim to fame on the horizon -- making the playoffs.
