So let me understand this...
LA let Korpisalo walk away and quickly signed Talbot, and gave him an NTC. But really, their master plan was to trade for Saros, with Talbot (and his NTC) as the back-up. That means Phoenix Copley gets waived and instantly picked up by another team. Wouldn't it have made far more sense to just not sign Talbot at all then? Acquire Saros and keep Copley as a back-up.
Also the minor issue that LA has $0 cap space. So even if Nashville retains 50%, LA has to send out $2.5M in cap to make this work. Who is being traded?
