On top of what others said, he was earning alot more PT than normal because others weren't playing well. Doughty, Camp, and Gray have been playing better as of late so that's where Walker's minutes were coming from. I think now we will bring in Walker for defensive purposes if any of those 3 are not getting it done.I feel like Walker never really plays much, yet when he's in there, he plays well. I thought he played well last night. Not sure why the quality minutes he gives us doesn't end up in more pt.
