The Leafs didn't do a good job with Schenn.
There were a lot of fishy rumours surrounding his conditioning and the push for the Leafs to make him a fridge on skates, and that's it.
His skating suffered, and it wasn't great to start with. It almost seems worse now.
If Schenn had footspeed, I still think he'd be a very good shutdown guy. Perhaps not 5th overall material, but that's a draft philosophy discussion I suppose.
I don't think the Leafs "rushed" him, per say, but I do think they did a bad job developing him. Poor strength advice, etc.
A lot of this is on Schenn, too. Obviously this is a lot of conjecture based on interviews and the like, but his attitude towards improving seems to be lackluster at best. He was touted as a hard working, down to earth sort of guy (good ol' Canadian boy), but he hasn't shown that work ethic. At all.
