Who was available that the Leafs did not get but was confirmed available? Who was this mystery unicorn perfect fit that the Leafs did not identify and trade for that for sure could have been had? Again you say with hindsight what they needed but what they needed wasn't available and their first choice (Brodie from CGY) was blocked by Kadri's NTC. Kerfoot was the 3c that they acquired to fill Kadri's role and imo hasn't done a bad job when he got to play in that role.
As for the cap thing, tell me who on the team is untradeable at this moment? Do we have any buyout candidates? From what I see the expensive players, while not ideal, are expensive because they are good. There is no unmoveable contracts and the team has a fully functioning 20-21 man roster as we speak. Where is the cap crunch.
I don't think anyone would take on Marner and also give back equal value for him in a trade. That contract will hinder any trade attempts. You're right, he is trabeable, but you want to win the trade if you move him.
As for Barrie, that was just awful and should alone have cost Dubas his job. Dubas clearly wanted Brodie, but then when he couldn't make that happen he settled for Barrie.
Why he was targeting soft RHDs and willing to move a 2C for that is beyond me. He should have been out there looking for a rock on D, not guys who are scared of physical contact.
Kerfoot isn't a good 3C, and what's worse is he replaced Kadri at 3C, but Kadri is actually a 2C. So Dubas' plan was let me go from a position of strength at centre and then end up with a deficiency at that position, and also supplement a team that needed to get tougher with a player who is softer than butter. But hey, it was an RHD, so must make the team better.
It was one of the craziest moves I've ever seen in my many decades watching hockey. Would love to sit with him while I have a beer and he drinks something with an umbrella in it and hear his explanation. Even worse, I would like to hear Shanny's explanation. At least with Dubas I can give him a pass because he has no idea about intangibles since he never played the game. But Shanny supporting moving to a team with the physical presence of a timbit team is hard to comprehend. Maybe those moves happened on days Shanny wasn't visiting Toronto.
