If Durant would still fit into that 3 years or less category, it would be worth considering. As it is, you're losing big time. CP3 and Durant will probably continue to put up comparably good stats. In the next few seasons, Durant will probably get a bit better than Paul, but for now, they're a draw. And Nowitzki is way better than Millsap. So if you're aiming to do well this year or even the next two years, don't take the deal. If you're just shooting for five years down the road, it's worth it, but that's so far away that things could change a lot. In summary, DON"T DO IT!
