Kempe does what he needs to do, but the fact is that we should expect bigger things out of Perlini and Crouse than Kempe, which makes Kempe one of the more likely players to sit once Dvorak returns. If Kempe were 4-7 years younger, then they are all in the same boat and any one of them could be expected to sit. At 30, I don't know if we are getting anything more special out of Kempe than either one of Perlini or Crouse.
I'd almost say a trade to open some room up is more likely than consistently sitting Perlini/Crouse over Kempe. Kempe or Dauphin also make more sense to return to Tucson than Perlini or Crouse, but it may not be as simple as that. I'd put money on Kempe being returned sooner, rather than later. Almost exactly how it shook out last year - Kempe was returned to Tucson in mid-November without a whole lot of reason behind it - we hadn't traded Duclair yet and he is one of those guys who just plays a simple, honest game but won't be capable of going next-level in the same way that Perlini has the speed/shot/size combo to do so and Crouse in the physicality and net-front presence area.
