NHL Insider predicts massive upheaval for Maple Leafs

This would be franchise altering.



So, what exactly will new Toronto Maple Leafs general manager Brad Treliving be doing with the "Core 4" of John Tavares, Auston Matthews, Mitch Marner and William Nylander?

If this prediction from TSN analyst Darren Dreger holds true, there will be a massive upheaval this time next year in Toronto should they once again fail to make a deep postseason run. 

While speaking with Leafs Morning Take with Nick Alberga and Jay Rosehill, Dreger expressed his belief that the Core 4 has reached "the end of the runway". He also appeared to hint at a coaching change. 

"I think that the Core 4 is at the end of the runway. I really, truly do.. I side with Shanahan and I side with Brad Treliving in recognizing the skill set of these players. Now, if the maturity moves up another notch... I think they can win with these guys, and if they can't, then guess what - when you have me on next June, there will be significant change, and it will come in varying forms and not just the roster."

The Leafs have already indicated that all four players will be back in Toronto next season, and it looks as though they'll be keeping head coach Sheldon Keefe around for at least one more season.

But based on Dreger's words, it all could come to a crashing halt next summer.
