TVA Sports: (through google translate) NHL player agent Don Meehan on offer sheets, and though rare, they are a bargaining tool for the agent/player.
“It’s still part of the discussion,” said Mehan. As you know, there has been no hostile bid for six years (Ryan O’Reilly, who saw the Avalanche match the Flames bid in 2013). It’s not something that happens often. But it’s part of the negotiations because of the salary cap.
“I would say that the probabilities are higher this year than at the last ones.”
