I think come the second half and then ultimately the playoffs, every big sans Garnett has to EARN their playing time. That goes for all three centers and BBD too (JO can back up KG).
Honestly, I don't care who you are (Perk), who you were (Shaq), or how much money you make (Jermaine). Whoever compliments KG's game the best should get the most minutes in crunch time.
I trust Doc with this.
