Maybe Allard + cond. 2nd?
2nd turns 1st if we reach the final or maybe conference final
I think that's a fair limit of what I'd give. 2nd+Allard/Carrier (or similar "B" prospect if there was one the Flyers liked better). Nobody would complain if it conditionally switched to a 1st if we made the final-4, I suppose... although at the same time that would hold us back from using the 1st in a different deal, which would be more my problem.
But I think the key again for the Preds is that it should be something of a buyer's market this year, there are quite a few wingers who may make the market, and I'd rather pile assets into a Stone pursuit too. Or consider how my comparison shopping pans out on other players like Nyquist, Zuccarello, Silfverberg, whoever else ends up on the market. Simmonds would definitely not be a headline target, and he would not draw any bidding war premium. He'd be more like a fallback option. And definitely not a player to even consider signing long-term, so purely a rental. The 2nd+B prospect or just standalone 1st are entirely fair in that context.
