I don't know but in a way that's sort of my point. I assume Sergachev would be part of the ask, the main part, and then beyond that...Point? A couple firsts? A prospect like Foote? What's the return for Ottawa that makes you say "wow, what a good return" while not doing serious damage to Tampa's depth for those cup runs?
I imagine an offer would be built around one of Sergachev or Point, and then picks and prospects thrown in after that. It'll be a big haul but after that one main part the trade will look like quantity over quality. For the very reasons that you've suggested. I can't imagine sens fans will be happy with what they get back. There's only going to be a handful of teams that will either a) feel comfortable acquiring him as a rental or b) have the salary cap structure to be able to offer him a mega deal once his current one expires.
It's sort of a similar situation we were in with Kessel, but their Ryan ask would be like if we demanded whoever acquired Kessel took Horton on as well.
