His 6 PIMs in 69 games comes across as a little soft and disengaged.
Statements like this always confuse me. And, always has traditionally - in the NHL -when talking about a player's "grit" or physicality. Isn't the idea to really NOT take a penalty and put your team down a man for 2 minutes or more?
I'd say hits would be a better stat for that, but even then, you can't rely on that as a "for fact" number since they seem rather arbitrarily (or randomly?) kept track of.
As for Sutter, I know he's capable of a little more offense as evidenced by his time in Carolina. I keep waiting for it to blossom in Pittsburgh. But, he has been rather un-noticeable on the ice so far this season.
