The Golden Knights certainly have their fair share of cap room difficulties, but Kane could come relatively cheap given his age. Furthermore, he has expressed a desire to play with a team that he thinks can win, and the Knights certainly have that going for them as they just won the Stanley Cup in 2023. Perhaps he would be willing to take a discount to play for a team of that caliber. SinBin Vegas writer Jason Pothier argues the Knights should target Kane in free agency.
There is a good chance Vegas is interested in Kane anyways. He played rather well for the Red Wings last season, proving that he still has it after he had hip re-surfacing surgery. TSN reporter Cheryl Pounder noted that every team should be interested in him.
As such, the Golden Knights will certainly have a lot of competition when it comes to signing Kane. Perhaps a team with more cap space will squeeze Vegas out due to their very limited flexibility. Be sure to stay tuned over the summer, particularly around July 1st to see where Kane will sign.
