Well, IMO Greg Marshall should go to Winnipeg. He has ties there from 2007-8 and only left because of Mad Dog Kelly.
I don't think Gibson is the right guy for the Argos. They didn't call him Powder Keg in Winnipeg for nothing.
Between Jones and Milanovich? I would go with the QB turned offensive coordinator Milanovich. But they both are unproven as Head Coaches.
This probably means Adam Rita is staying as GM. I thought at one time the Argos were just waiting for Eric Tillman's court case to be resolved and have him replace Rita. However, with the latest turn of events that is not looking like a good scenario at this time. One thing they might look at is to have Tillman replace Greg Mohns for a year or two and then replace Rita.
Tillman could keep a low profile and bring in some much needed talent to Toronto in the mean time. When things blow over, and it always does, Adam could retire or be given an advisor role.
