Leafs are out. Can't afford him with his contract extension next season plus their own RFA's coming up.
You're simply not getting enough back from Montreal.
San Jose is kinda fair, more or less just a switch of scenery. Not sure San Jose wants to do that cause they love Couture there.
Minnesota is an interesting option. I'd make sure Mikael Granlund is coming back to Dallas tho as the guy to replace Seguin. Not sure you'll get Brodin from them though, their defensive depth is lacking and they can't afford to lose him.
Islanders are in rebuild mode so I doubt there's interest in giving up young guys like Bellows or Wilde.
With Anaheim, just like Montreal you just simply aren't getting enough. Perry is washed up so its basically the 2 young guys and a 1st. Seguin can get more than that and should get NHL ready players back, including at least 1 dman

How do you get to trade 6 Seguins? Does he have a lot of brothers or something?

Just hypotheticals... see how I also didnt actually receive any of those players back either. Just the Leafs trade which I tested for JonesRyan

What would the hot take on Benn be?

Depends on who needs a power forward LW. Benn is 28 and "Underperforming" with the Stars (still has 30 some odd points through 38 games).

Toronto could be interested?
Potentially Boston for their 2nd line?
Maybe Carolina for their 2nd line, but I believe they ultimately need a Center
Nashville could use s spatk as half their lineup is injured
