Because, he is going to get 7.5mil + on a contract, which is overpay for what he brings, which isn't much outside of points. He isnt great defensively, and cant drive his own line. Zero interest in paying a player that much who doesn't bring more to the table.
I doubt Kane would be the only player they bring in.
I don't think its a big deal if Bedard has the same linemates he did last year. Having more depth behind him is the issue. Teams can just solely focus on Bedard, and not have to worry about anyone else. If they bring Kane in, that gives other teams another player to think about on a different line.
I'm not huge on bringing Kane back myself though, for the reason that I don't think they should play together because both are terrible defensively.
True, (depending on the salary of the contract that is), because it doesn't cost you major assets to acquire him lol
