Getting rid of a star player in the middle of a season doesn't happen often but when it does it's usually an all-or-nothing move for the coach/GM.
In 2006 after five games Wally Buono released Antonio Warren who was the league leader in rushing TDs the previous year. Nobody picks up Warren and BC wins Grey Cup behind Joe Smith. Buono regarded as a genius.
In 2009 after four games Bart Andrus couldn't deal with his best receiver Arland Bruce and dumped him off to Hamilton. Argos finish 3-15 and Bruce puts up huge numbers in Hamilton. Andrus fired at the end of the season and is universally regarded as one of the worst coaches in CFL history.
In 2011 after five games Marcel Bellefeuille couldn't deal with Arland Bruce, who was coming off a 1300yd season, and dumped him off to BC. Bruce goes on to win a Grey Cup and Bellefeuille fired at the end of season and remains out of football.
Maybe getting rid of his star RB is exactly what Milanovich needs to get his high flying offensive system going. Maybe Boyd will flop in Edmonton and justify Toronto's assessment of him.
My take is that Toronto made a terrible decision to release Boyd and it's not going to do anything to get their offence on track. As an Argo fan, I hope I'm wrong and Milanovich/Barker turn out to be geniuses for the move.
