The Canes have been scouting the Leafs since early in the season. They’re scouting someone off your roster. I don’t think you can say that they wouldn’t use someone off the roster in a trade.
pro scouting is really common and I can see why the Canes would scout the Leafs being that the Leafs have a lot of offensive depth that the Canes could use, but that doesn't obligate the Leafs to make any of those trades, and I think we can agree that scouting has not been regarding William Nylander as he hasn't been playing in any of those games. If the purpose of assembling a team is to compete for championships, it doesn't make much sense to me to take a team apart right at the beginning of its window to compete while everything is going well
I think the best explanation for all of the scouts being in attendance at once is that the Leafs have signaled that someone on the roster is available, and to me it would make sense for that to be Jake Gardiner being that it looks like Dermott is ready for his minutes and we're likely to lose Gardiner anyway. I could also see guys like Brown or Hyman being made available as the more expensive complimentary pieces that have their contracts due for renegotiation and raises in the next couple of years.
I don't think it makes sense that they are all there to find the additional pieces in a larger Nylander trade because Nylander is very valuable in a vacuum, and if the player we were to acquire for Nylander was more valuable than him the additional pieces are not likely NHL roster pieces but prospects or picks. That was the premise of that string of conversation, that it probably doesn't have anything to do with Nylander
