I understand the points you've made about Len. But making him a starter because he has proven to be a horrible backup (in your words) doesn't sound like a Suns step to success.
Len had the chance to prove himself against bench players (2nd tier players) and he didn't with his inconsistency. So let's make him a starter? I don't see it as motivational or effective. It reminds me of the old joke -- He's too drunk to sing. Let him drive the bus.
With all respect, it sort of perpetuates the Suns seven year standard of overall mediocrity.
That's not exactly my point. Alex was horrible in preseason, the worst we've seen from him and probably led to the team and agent not reaching an extension. I don't think there was anyone left in his corner on this board, or maybe anywhere. He began the season playing just as poorly but after game 7 he was moved into the starting lineup.
He struggled in his first start but from his second start forward, he began playing very well for the next 10 or 12 games with Chandler still out. When Tyson returned, Len continued to start and still played okay until Chandler had a great game as Len's backup. They then switched positions and Len's performance dropped almost immediately as the backup. He's been very up and down since then, mostly because as a backup he seems prone to pick up early fouls and his minutes have been very inconsistent as a result.
So, he's played better as a starter, he gets more minutes as a starter and we're about to have to decide on his future with our team as a starter. I maintain we need to start him the second part of this season to help us come to a decision about him (us, front office, not us, you and me). Chandler, despite some gaudy rebound numbers, really hasn't played all that well this season.
I don't use anything but the most basic of stats but it's my understanding that Len has much better advanced stats, especially rim protection. Regardless, the eye test shows that Tyson simply cannot defend the paint anymore and he can only rebound his immediate position. He can no longer get to those rebounds that don't come almost directly to him.
And Tyson gets worse as his minutes go up. Len is the opposite, his play gets better as his minutes increase. So, Chandler, to get the best from him on a per minute basis, needs to have his time limited. And Len, to get the most of him on a per minute basis, needs to be the regular starter. Seems like an easy call to me, trade Tyson or move him behind Len.
