Wow, is anyone else wondering who the **** OLE-KRISTIAN TOLLEFS is?
It's also "Tollefsen" which may have added to your confusion. Love to have him on Montreal, by the way, not just because of his name, but also because he's a huge hitter, a little like Komisarek's style.
The problems with stats like Hits, Shots Blocked, etc. is that not every arena counts them the same way so you always have to take it with a grain of salt. If I remember correctly, three players from the Habs were in the top ten last year which goes to show you that the stat is not perfect.
