There's very few instances of a playoff team asking a player mid-season if he wants to stay, then trading him at the deadline if he doesn't. That's what I was talking about when I said no one does this.
And trading players who are going UFA in a year - that doesn't happen that often, although that's more common (Burns, Cammalleri, I think Tanguay, Staal, and plenty of others).
Sure seems like given the leak about Letang being dealt that they are trying to use his desire to stay in Pittsburgh as leverage.
ah well thats not what i was suggestion or referring either really, like i said its more just like what shero is doing now, if he sense that there's no hope for Letang in Pittsburgh in the future its better to know it soon enough to play your cards the right way to get maximum return without hurting your team too much immediatly if you can.
