Only reason to do that is if JB is targeting a specific UFA and needs the cap space.
Personally, I wouldn't and just ride out LE contract. Just 1 more year and be free of all the bad contracts. This team was able to go deep in the bubble year. I can't believe that it was solely based on Marky, Tanev, Stecher, and Toffoli.
This season was a disaster with a compressed schedule, no training camp, no practices, and the whole team got Covid-19. So it's a mulligan.
I expect a rebound to make the wild card spot (or just missing it) next year.
