Chiarot is a very solid #4 guy. He's no longer a bottom pairing guy but if he plays there, that means the team he is on is deep and a very good defensive team.
People can try to pessimistic or ignore all they want. Chiarot brings physicality and he raises his game in the playoffs. He don't provide too much offense but this guy can skate for a big man and he will drive you nuts in front of the net and along the walls in the playoffs. He's a physical beast that skates very well. Those trusted/mature types are not readily available.
The Habs didn't go on that run solely based on Price. That top 4D of Weber, Petry, Eddy, and Chiarot were very tough to pernitrate. Chiarot was a big factor in playoff series wins against the Pens, Leafs, Jets, and Knights. That is not to be taken lightly
No idea what he returns (1st or two 2nd's or something else) but whoever gets him, is getting a edge on the back end for the playoffs in terms of protecting their goalie and playing sound D. Reality
