Not to - but Porter is the youngest of the 4 and has the fewest health questions. If you are going to take on a bad contract, those are importent considerations.
That's an assumption on Porter as he has now been with 2 different teams and pretty much the same results. Now, I do like Porter, but we are a year away from losing some large contracts off the books and gaining some flexibility and like any trade, it depends on what it would cost. Porter will also be a free agent the same time as Lillard, McCollum and Nurkic. That would be 4 large contracts that would need to be dealt with.
