Those are some pretty insane (ly unreasonable) expectations for a return in a Stepan trade.
But trading him for 2 prospects and a pick (the later of their 2) is reasonable?
I don't know why the RoR trade was used as a comparable (and even he brought back 2 NHL players, as flawed as they may be) when the situations weren't remotely close to the same.
I've said this at least 3 times and I swear this is the last time I'll say it: If Stepan is moved you are going to be very surprised by what he returns.
