NYI just traded for Romanov and they have Dobson, Pelech, Puloch, Aho, Salo and Bolduc. Chances are they won't be able to re-sign Mayfield and now he's sliding down to their 3rd pair and had an underwhelming year last season. I could definitely see him on the move.
Who knows what will happen with HC stuff but there's smoke, I never mentioned it would happen at all, I actually mentioned possibility which means there's no indication either way at this point but there is a possibility with what's been out there so far. If NYI can trade Mayfield to get a team to take Bailey when half the league is at the cap or over then it makes a lot of sense since they can replace him internally easily with what they already have. When you consider the Kadri rumour it does make sense.
Sens have picks/assets they could deal and would be one of the few teams that could take these players without sending any salary back. In any case it's all speculation. To my initial point though, it makes a lot more sense for them to trade Mayfield than it does for them to trade Puloch. I'd trade Hamonic before Chabot even if the end goal was to get Kadri. Puloch is a top pair D making 6M a year long term. No one is trading that. Mayfield is not in a NYI sweater past this season.
