Top prospects are rarely, if ever traded for rentals, so I'm not sure where the idea that the Leafs would need to give up Cowan is coming from regardless
The only way I could see a guy like Cowan, Minten or Danford moved is if we're getting a young cost controlled 2C back, or a long term partner for Rielly
I think you can justify paying a high price if you're getting the ideal player of need back, like the Horvat deal for the Islanders
I'd still probably just get a guy like Dvorak, who I think is going to be cheapish and whilst not a world beater would be useful if we run into injuries
