Was really underwhelmed by his impact. Aside from the big hit on Kukan during the play-ins, he was useless in every facet. I guess the concussions have really limited his nastiness.
I will say, though - if this management team continues picking up random "tough" pieces in Martin, Boyle, Clifford, etc. and plugging them in to a mismatched 4th line in the hopes that it adds some sort of physical presence, there will be no progress made in making this a tougher team to play against.
Clifford was never going to look good playing beside Spezza, Gauthier, Engvall, etc. He needs likeminded bangers on that line. The main reason the NYI 4th line is so effective is because the line has an identity, something the Leafs 3rd/4th lines have none of. It's just skilled players thrown into a blender together.
