Hindsight is 20/20, and perhaps we will never know what would have happened if certain teams drafted differently, completed a trade that was on the table that ended up being rejected, or a player never had some kind of injury.
Still, you can't help but wonder - what if?
What if the Toronto Maple Leafs and Pittsburgh Penguins had made a different trade for Phil Kessel in 2015? Well, a former Toronto Marlies assistant coach and video coach, and current The Athletic writer, Justin Bourne, revealed that the Penguins had offered different prospects in the deal, and it was up to Toronto to choose which one they wanted.
This conversation occurred in Craig Custance's The Full 60 podcast - it was revealed that Toronto indeed had their choice of players to take in a deal that eventually saw them receive a 1st and 3rd round pick, along with Kasperi Kapanen, Scott Harrington, and Nick Spaling.
Only Kapanen remains from that deal.
But Bourne revealed a bombshell of a detail in those discussions. He explained that there were a couple other players offered in the deal, one of them being Matt Murray.
"There was a scenario where he comes here, and that's before they traded for Frederik Andersen," Bourne added.
Can you imagine what happens if that trade transpired the way it did? It's hard to know how things would have played out, but if Matt Murray was a Leaf, would they have ended up in a position to win the draft lottery and select Auston Matthews that year?
Would the Penguins have won back-to-back Stanley Cups in 2015-16 and 2016-17?
There's no knowing because it didn't happen - but Toronto had the choice. They could have had Matt Murray in the deal that saw Phil Kessel go the other way.
History could have completely changed.
Maybe Marc-Andre Fleury is still a Penguin.
