If Toews is a bit ticked off at Hawks and needs a cooling off period with current management, I don't blame him. Captains the team to three Cups and then is unceremoniously (well I guess they did do that whole ceremony which was probably annoying for him if it was involuntary) dumped when he likely have been willing to come back for nothing. They bring in Corey Perry of all people to be the old guy mentor and look how that turned out.
Toews & Kane unfairly got grouped in with the whole Brad Aldrich stuff, even though they were like 21 years old at the time. None of that was even remotely their fault, but you see people on Main Boards as always making digs at them for it like they were the perpetrators. Fact is current management wanted a "clean slate" from all of that scandal and probably viewed Kane & Toews as being representative of it for being the public faces of the team.
