I guess I'm somehow missing the suggested alternative returns for Miller. The common theme I see from Canucks fans is Schneider... and the common response I see from rangers fans is an emphatic no. I don't think I've seen a realistic proposal from a Canucks fan not from NYR/TOR.
With respect to the prior comparisons to Stone & Pacioretty, while I'd agree that Suzuki & Brannstrom at the time were likely viewed as marginally better prospects than Robertson is today, neither of those deals included a 1st round pick for the Habs/Sens.
No disrespect intended for Miller at all.... maybe Mark Stone is the best comparable (although I think Stone had more desirability than Miller does) and somebody is willing to send a prospect at the top of their list at the deadline for him; but I don't think it's going to include a 1st as well, and that prospect is likely going to be a year further away from contributing than one that you get at this deadline.... and that's assuming that Miller's play continues.
They were considered top tier prospects. Robertson is simply not there.
If we fall backwards into a prospect like they were considered though, I agree a first is not being included, barring other dimensions to the trade.
