Tampa's situation with Kucherov was a bit different however....Same for Vegas with Stone. Neither of those players were forced to retire, so both teams were able to use the additional space to bolster their rosters. Both were rewarded when the players returned just in time to start game 1 of their respective playoffs.
If Chytil is forced to hang em up & we didn't trade his deal, sure we could use his cap space, but we wouldn't really benefit like those two teams did. Plus we'd be stuck in a situation for 3 more years where we're not accruing deadline space. It's not an ideal situation which is why we'd likely pay Arizona a few draft picks to take his contract. It's not costing them real money, so I think two 3rds would be the price.
I'm pretty sure Tampa carried/is carrying Seabrook so they can have the additional space.
They've been masterful in their maneuvering of LTIR.
