Boston Bruins general manager Peter Chiarelli was a guest on WEEI here in Boston with the Dale & Holley Show, and he concluded his interview by saying that the odds of him making a trade before the March 4 deadline is “60 to 75 percent.”

Chiarelli also acknowledged that he has around $4 million in cap room to work with because of winger Marco Sturm’s LTIR status while he’s out for the season after knee surgery.

But Chiarelli’s best revelation came when he was asked about re-signing one of his goaltenders — upcoming unrestricted free agents Tim Thomas and Manny Fernandez.

“I’m not going to comment on negotiations, but generally speaking, it would be prudent if I did (re-sign one of them). But I don’t comment publicly on negotiations,” Chiarelli explained.

MK: Of course, from what he didn’t say you can deduce what he would’ve said had someone slipped him some truth serum — he’s working on signing one of his goaltenders. And it’s widely accepted that the one the Bruins want to stay more is Thomas.

Starting with Fernandez’s continued inability to stay healthy over a season and continuing on to Thomas’ history as a goaltender that’s accepting of sharing time (which would mean a tandem with Tuukka Rask next season), it’s the only move that makes sense. Let’s face it, even if a deal gets done before the season ends, the Bruins wouldn’t dare let it leak out and risk offending Fernandez.
