Quoting: TrueCanuck
Thank you for making my point even clearer! You've stated that Mayfield is playing bottom pair but was able to move up when needed (as I stated). Dermott has done the same thing. The difference in ice time? Toronto hasn't been hit as hard by injuries so they're able to keep Dermott in his spot.
Side note, I never said that either team should make the deal. I just said that the value is more than fair 1 for 1.
Not sure if I didn't make myself clear enough in contrasting the two or you're just digging your heels in, but let's dive deeper then.
Mayfield has spent nearly 66% of his ice time this year playing alongside Adam Pelech. At even strength, they have out-chanced, out-shot, and out-scored their opponents 21-14 for a team that has generally had negative possession numbers and has been outscored 77-88 otherwise at ES. So it's not just like Mayfield was moonlighting on the top pair - through basically half the season, he has been the most frequent RD1 for the Islanders, with solid possession numbers. And again, he might show as RD3 on DailyFaceoff but he's playing on a team that rolls all 3 of their D pairs equally (for example, last night he was 2nd amongst Islanders D in TOI behind...Adam Pelech.)
Dermott has spent about 18% of his even strength time with Morgan Rielly, who we can agree is probably top pair on TML. Together, they have 47.5% of chances and 43.5% of shots together, while at least maintaining scoring equilibrium (5-5) for a team that typically gets 53% of the shot attempts at even strength. The only other skater Rielly has worse numbers with (minimum 20 minutes together) is Rasmus Sandin, the other 3rd pair D for Toronto. That's fine! They're both bottom pair guys, Rielly is only one guy (hilariously, his possession numbers when skating as the only D at even strength are actually better than when he spends time with either Sandin or Dermott), and there's only so much he can do to cover for his partner on D.
I agree that there's really no sense for the deal to be made, even if it's Mayfield for Dermott and a 1 or 2. Dermott fills a hole on the left, sure, but opens one up on the right that the Islanders don't have anyone to plug it with. And Mayfield doesn't really fit the kind of game Toronto plays - I'm sure he'd have success in the playoffs when things slow down and get more physical, but until then he'll be a square peg in a round hole. But I gotta push back on the idea that Dermott and Mayfield are equal in value and would be a fair 1-for-1 deal.
