He does most of the work there already though afaikTreliving is by a mile the best GM available.
People who want Tulsky - a rookie GM - to run this franchise a month out from having to re-sign Matthews, and make decisions on the core four are out of their minds.
He doesn't have experience being the man at the top - negotiating contracts, negotiating deals around the league, dealing with the media, fostering relationships with other GMs, Managing culture, etc .
He would be coming from a AGM role in Carolina (lol) to TORONTO, the biggest/highest pressure market in hockey.
