So far the Penguins remain quiet in the trade circuit, but there are a few minor moves worth mentioning.
For starters, the Pens sent Wilkes-Barre/Scranton defenseman Danny Richmond off to St. Louis in exchange for Andy Wozniewski. Hooks put it best, "Depth for depth." If anything Wozniewski has a bit more NHL experience, but that comes with the territory when you play for an open team like the Blues.
The Penguins also claimed Craig Adams, formerly of the Chicago Blackhawks, off waivers. Adams is a right winger who tallied 35 games (2G, 4A) with the Hawks this year. He spent a good amount of time with the Carolina Hurricanes before shipping out to Chicago. He's not a young guy at 32, but he'll likely add a little depth and experience.
