The agent for Lightning forward Sean Bergenheim certainly made it sound as if his client, one of the best stories of the postseason, is on his way to becoming an unrestricted free agent.

Todd Diamond said Friday the sides have "right now agreed to disagree" on a new contract.

Asked if he believed a deal could get done before July 1, when Bergenheim hits the open market, Diamond said, "It's not going to be easy, but stranger things can happen."

Bergenheim, 27, who made $700,000 last season, had 14 goals, 29 points in 80 games, but exploded for nine goals, 11 points in 16 games in the playoffs.

"There's no negativity," Diamond said of the negotiations, "other than putting together a financial package everyone is happy with."
