Offer Sheet, the Weapon of Choice?

Just a thought I had. In this era with a salary cap, Clarke was the first one to pull the trigger on an offer sheet. According to TSN, Clarke tried many times to acquire the young centerman Kesler) but was always denied by Noonis. This first offer sheet occur in the Western Conference. So, in my mind, it's not a bold move, at all, from Clarke. I think it will be very interesting, in the future, to see how general managers will use this offer sheet as a strategy to put someone, his own conference, in trouble regarding the cap. In that perspective, who will be the first GM to use that strategy in the Eastern Conference? Garth Snow with the approval of Wang?
