I can't speak much to their OL, except they looked ok so far, pre-injuries.
But if SSK regresses in '22, the community is going to clamor for heads. Cody and/or Dickerson The Lesser could get the axe.
I don't think SSK can have a "oops, injuries" or "rebuild" year. They need to go for it now. Look for desperate FA/trade moves if their OL really is in trouble. Heaven help that club if WPG beats them in a WDF again...
I hope they do, then there will be many tickets for sale for the Grey Cup
