Yep count me in as pleasantly surprised with this call up. I think Tynan just needs a chance to play top 6 on a really bad team before anyone is going to give him a proper chance on a good team. The Avs should do him a favor and trade him to Ottawa or LA or something, or just keep him as an AHL veteran.
Dries at least has a chance to develop into a good 4th liner. I can't say I've seen anything yet that says "NHL" from him, but the dude can score at the AHL level (20 goals in 47 games this year), so if he can contribute at, say, Bellemare's rate, then he could be a good depth player for us.
Btw, I agree O'Connor would be a better callup, but I think he's injured. His last game with the Eagles was Feb 16.
