In an unusually late announcement, the Colorado Avalanche have agreed to send defenseman Chris Bigras to the New York Rangers for defenseman Ryan Graves, per BSN Denver’s Adrian Dater. Both players will remain at the AHL level for now. Bigras, 23, has actually played in 46 NHL games, including 15 this season. However, the 2013 second-round pick has not shown enough ability and upside to warrant keeping him at the top level in a regular role.
