It won't even be possible to compare at the end of the season. It will be hard for Ken Miller to turn it around when he's taking over in mid-season and has no OC in place. I suspect the players will be motivated under him in a way they weren't so far. Had he been coaching from the beginning of training camp, I doubt they'd be 1-7 now, but who can say for certain?
But the only real comparison is the one we'll never be able to make: a full season under Marshal vs a full season under Miller. Since you can never know the answer to that, you have management there to exercise their judgment and make the best decisions they can.
Not a happy time in Sask. these days.
