Jake Gardiner is honest about possibility of not returning to Toronto next season

Thursday, the Toronto Maple Leafs cleaned out their locker after a first round exit after they lost Game 7 against the Boston Bruins and Jake Gardiner was open about the possibility of not returning to Toronto next season.
A member of the Leafs organization since 2011-12, Gardiner hasn't played for any other franchise. But all this might change this coming off-season as he will reportedly ask for at least $6 million, according to Darren Dreger.
It's definitely an emotional time, potentially leaving here and happy with the guys who've been here for so long. I think even my wife, she was pretty emotional yesterday. It might be the last time we're here, we'll see how it goes. If there's a chance to come back, we'll see. 
 Do you think Gardiner will be back with the Leafs' organization next season?
