So this deal is predicated on us signing a free agent that we could very well end up signing anyways? It's not like we don't have the cap space to throw an offer at Panarin right now. Also, it's not like GMJB isn't capable of moving contracts out. We may be stuck with Eriksson, but a guy like Sutter could still be moved. Hutton's rights can be moved. Edler may not be resigned. Tanev could be moved. There are options for creating even more cap space if GMJB wants to without shipping out the best RW we've had since Bertuzzi was in his prime.
And besides, what if Panarin sees that Boeser is gone, knows how badly that will nerf our forward lines and affect our overall place in the standings next season, and says "Y'know what, no thanks"?
