Since Melnyk is not interested in selling the Senators, I don't see how they can be in play. Even with the circus show and declining attendance the past many seasons, the fact they own the their arena, they would still be better off staying there than paying rent in a building Fertitta controls.
If he wanted to sell. At least one offer was made, rejected and reportedly around 400 million. With Fertitta looking for a deal, would he pay that much plus a relocation fee to the point where more local interests won't match? I highly doubt it.
Plus if the 'right team' means a competitive one, the Senators in most years will be the furthest thing from that as long as Melnyk owns them.
