Why is he available

I think he is a good player but rather because Colorado has a surplus of puck moving defensemen and want to balance the roster?

1) he is not
2) Chambers of the Post wrote an opinion piece saying Girard maybe expendable because of the emergence of Byram.
3) Hockey Writers a compiler spin site took that and ran
4) do you really think a top young puck moving dman locked into a contract that already only makes him the 55th highest paid defenseman for the next half decade would only be worth an overrated 2nd line wing who had unspecified issues that made him leave the team during the playoffs who also makes more than Girard and a throw away pick
5) the Avs literally laugh and say yeah we will just keep him for the next half decade.

He isn't. It's speculative that he may have been on the table for Eichel. Unless someone else wants to move an Eichel caliber player, I don't think he's traded anytime soon.

Hopefully a new rumour starts by some no one and this non sense goes away… how about the Bruins looking to ship out Carlo?

Before last night's game I would say almost any depth piece is available, and girard fits that tyson barrie most expendable value piece on the blueline
