I just don't think there's any high level archetype that explains why Hardy favors one player or another. If there's one player who has a long leash, there's probably another player who plays just like him who can't get off the bench. The real reasons are probably behind the scenes that we can't see. It also changes quickly and all the time. Ochai, Walker, and Key have all been the golden boy and the on the **** list at different times.
If I'm being honest, I think Hardy did a pretty good job at distributing playing time for development even if some decisions felt weird or unexplainable at the time. I think all our guys got enough playing time, and that's what you should expect from a tanking season. The only decision that really made me uneasy was just how much he loved Key. We don't call him Lisan al Ghaib for no reason. But I think Hardy has corrected that (or ran out of patience) and I'm more comfortable with Key's current standing.
