The problem for me isn't about whether to play rookies or not, but whether they're playing them when logic dictates.
For example, early in the season Stevens played the young guys a lot. We struggles, he made away with that. No problem there considering the depth.
As the season went along, our big man rotation showed flaws and some depth issues as far as players playing at a level that warranted playing time. During those times Mickey could've gotten an opportunity. A problem here though is that depth didn't allow to Mickey to be dressed in the first place.
When injuries hit though, perfect opportunity to test Mickey, no chance was given despite Young & Hunter having a lot of opportunities in the year. So that's the only issue with Stevens.
But since he got here he's given rookies their fair chance, most have failed when called.
To keep it in this cotext, my beef with Doc is mostly with the Giddens/Walker era because logic dictated that at least one of them should've been integrated to the rotation throughout the season. Why? Because we lacked a lot of depth in those positions. So he had to make due with what he had and he didn't use them. The consequence was that we had no other alternatives to defend other SFs in the playoffs, like Lewis, and also he fatigued our main wings.
