Transfer Portal yup, interim basis until the MWC schools join the "PAC".
If Pinnick doesn't mind living in Pullman I won't lie and acknowledge it's a step up if he's getting six figures at least and a reasonable chance to start next year. I imagine it's something akin to starting at Boise or Fresno in terms of profile, resources, facilities, etc.
On the flip side, if it comes out that his actual compensation wasn't that great (compared to say the offers after another year of FCS development) and he doesn't get to be a starter, I can see this being a gamble that doesn't pay off.
