Not really part of Rangers roster build, but just to respond, I think the Leafs are too early in their rebuild. Like any anxious franchise, they are trying to leapfrog the road to success. I was actually a bit incredulous to think that most people did think the Leafs considered themselves a real contender this season. I thought that was silly, even though they had made some good draft choices.
The problem that the Leafs have is that, in most cases, you can't leapfrog and skip the real building process. Plugging John Tavares in (check off the proven experienced scorer, hometown boy too...we got it!). Grabbing Muzzin (okay, heavy physical playing experienced Cup winning defenceman...we got it!), installing Mike Babcock as coach (cost is no object, we want the best....done!).
Leafs could have made a move to get Nylander to Winnipeg for Trouba. From all I heard, that could have been done had the Leafs wanted it, and that the Jets were willing.
The fact remains that the Leafs did not think it was necessary.
I am just a rank amateur observer on team rebuilds, but Gorton has done a very good job by doing the real work, and mostly, I get the sense that he knows that you can't cheat. Luck is part of it, but don't rely on pushing it.
