Grimaldi has been one of our best players this season. That's... well, that's a sad thing to have to say. After Josi and Bonino, he has brought a consistent effort and spark every game. He chips in offensively. But if you're 5'6", an impending UFA, and not really a big producer, I don't know what the market value really is. Basically like Soundgarden says above, 2nd/3rd maybe, in which case worth more on the ice to us if we have any hopes of re-signing him.
Hamhuis is veteran depth at this point. He's near the end. In a limited 3rd pair or spare role, he's serviceable depth. But I don't know what a team really pays for that. A late round pick at best?
