Having offersheet offers and signing offersheet offers are two completely different things.
There were probably offersheet offers but MM didn’t sign any of them.
The question and discussion should not be whether or not did any teams OS MM but rather what was the caphit and term of such OS. How likely would teams offer something similar or better to what Leafs offered? Would that number be more than what they signed for at the end, which was the 7th highest paid player in the league and 2nd highest paid winger? Also what about terms and NMC/NTC? Lastly location of said teams?
This is not hindsight, but if I was Dubas, I would dare MM to sign the OS and then evaluate whether or not to match.
Don’t think Ichiro was never top 10 in salary
