The Blues have been dragging their feet with Carlo Colaiacovo. They've never told him no, he wasn't welcome back -- but they never fell all over themselves in re-signing him, either. The team's been eager to upgrade the defense this off-season, and the opportunity hasn't shown itself, so I have a sneaking suspicion that a good number of Blues fans figured that the team'd suck it up and offer him a deal to maintain the status quo.
Turns out that might not be happening. A report from Brendan Savage of MLive.com states that the Detroit Red Wings have offered Carlo Colaiacovo a two year contract at $2.5 million a season, apparently because Jay Feaster's asking price for Jay Bouwmeester was too steep. Colaiacovo is a good defenseman, but probably not exactly the upgrade at defense the Wings were looking at this off-season.
It's a harsh consolation prize for Wings fans, who saw legend Nicklas Lidstrom retire and the team miss out on both Ryan Suter and Shea Weber. Colaiacovo is very injury prone and misses around 15 or so games a season for whatever reason.
