Excellent coaches you had there Slash although I would hate to lose Lowrey. I feel he should stay with the Hitmen for a couple of years for more experience although if he gets the chance you can't blame him. My first three choice was Sutter.
#1 is Brent but not sure if he can get out of his Devil's contract so
#2 is Darryl. If he flops then he will be toast (Both position). And with the million dollars to Keenan it will be tough to go outside to get a proven coach. Especially harder with the Brent rumours hanging over whoever takes the reign. Choice #3 is Duane if doing both jobs will be too much for Darryl.
I had McGill as the most likely non-Sutter option with Lowrey taking over Abbotsford (if he leaves) Never did put Boughner in the equation but an excellent choice.
