My pool is very similar to yours, points-only and very similar size.
I offered the Benn owner in my league (about a week before he signed):
Skinner straight up, he countered by asking for my Erik Karlsson.
I offered Bobby Ryan straight-up....and he countered by asking for Skinner and Ryan.
In other words, I'd have needed to knock his socks off to get Benn.
Same for you. If multiple guys want him, work them over and get a good deal.
From my standpoint, I'd want Parise or Toews, but I'd make sure every interested owner is involved, in order to maximize the return for Benn.
As for OV and a 2nd..uh..maybe.
Just have no idea what to make of Ovechkin right now, so I honestly can't give you an answer. Part of me says there's no way on earth you say no to the deal...but the other side really, really, really thinks Oveckin is just a complete lost cause right now.
