Ryan Callahan seems interested in testing the market as an unrestricted free agent in the offseason, but his agent believes it's entirely possible Callahan stays with the Tampa Bay Lightning after joining the team at the trade deadline in March.

Agent for Ryan Callahan said every report his client has given him about the Lightning is 'positive,' and team 'in the mix' for next season — Damian Cristodero (@LightningTimes) April 24, 2014

Lightning general manager Steve Yzerman reiterated his intent to resign Callahan on Thursday, saying "I like the way he plays."

Callahan did not record a point while facing tough competition and making a lot of defensive-zone starts in Tampa Bay's first-round playoff sweep at the hands of the Montreal Canadiens. He had 11 points in 20 regular-season games after joining the Lightning.

Callahan's cap hit was a little over $4 million in the final year of his current contract and he could be looking for a substantial raise considering what David Clarkson - a similar type of player to Callahan - received from the Toronto Maple Leafs last offseason.
