Trade one player on your team for the same number. For example, for the Rangers, trading #40 Hamrlik for #40 Grabner. For the Jets, even though I really like the kid, I'd trade one Alexander for another, #8 Burmistrov for #8 Ovechkin. The player is immediately signed to a long-term contract with a NTC, so you can't trade for some number and immediately trade him for a different guy. I'm thinking that ignoring the cap would make this more interesting, but I could be wrong. If you want, you could post a cap friendly trade as well as an "ignore the cap" type trade.
I'm sure another Rangers fan can come up with a better trade than the one I posted, but I'm a big Grabner fan, so that's the one that came to mind for me.
I haven't posted a stupid thread in a while, so I thought it was about time.
New Rule: If someone has traded for that player already, he's off the table. Also, currently active players only, AHL players are acceptable to trade.
