He can, but I'm not sure if it's wise or in the best interest of the team or Prohm himself.
I was fine keeping it under wraps until now, but it's just kind of weird that he came back, then there was supposedly some good vibes meeting, then he is out again. If we had the bodies I'd be fine with it because Burton is obviously improving with more minutes and more responsibility to produce...but we clearly don't have the bodies especially inside. It better be some seriously stupid crap McKay is pulling to be back in the doghouse again.
