You (not you personally godsshoeshine, the general you) are telling me both teams wouldn't jump at:
Capitals
William Nylander
Connor BrownJames Van Riemsdyk or Tyler Bozak
A Prospect
A 1st Round Pick
Maple Leafs
Ovechkin
A 3rd Round Pick
Maple Leafs jump into legit Cup contention right away, pair the last 3-4 elite years of Ovechkin with Matthews, Kadri, van Riemsdyk or Bozak, Brown et al.
Caps get younger (and acquire guys who will be RFAs in next negotiations), shed 8.54.8mil in cap space (hello Shattenkirk and Oshie potentially returning), extend the window of the team overall.
There are trades to be made.
EDIT: Looking at Capfriendly, I thought Maple Leafs were more fungible on cap space. Probably have to send Van Riemsdyk or Bozak back instead of Brown and both have modified NTCs (I can't imagine Caps would be one of the teams specified on either).
