If it wasn't a lack of effort, we'd hear about him going HAM doing power skating training. It's literally his worst attribute and we haven't heard of him putting in any real offseason work in it. In fact, we barely hear about any of his offseason training.
I don't think it's ALL a lack of effort, but I don't see him doing the work required to play at this level, either.
I just don't get him at all. It could just be he's getting horrific advice, I guess, but regardless - it sure comes off as this is at least partially effort-related.
Dude sucks. Time to move on.
