Generally, for me, it's based on Hoopla 1 and Hoopla 2, neither of which ended with the result we wanted.
Logically it's a sound move when looking at stats. I worry about changing the tenor of things when things are going well.
The players seem to like Comrie. They would be expected to continue to play well in front of him for one freaking game. It might even be a call to arms... Win one for Comsy.
A slight worry I would have is messing with UPL's head. He is the man now and should be treated accordingly.
Also kind of unfair to Levi to throw him into this situation.
