Two themes are emerging. First, is Harden still an "MVP-Level" player. I don't think Harden is going to win another MVP but I think it is a mistake to think he won't play at a very high level, say top 10 in the league level, for the next couple of years. I don't see him as even close to washed up or anything.
The second theme is who would you rather have, Simmons or Smart/RWill. The problem is that there is a huge gap between what Philly seems to think Simmons is worth and what they probably should expect to get for him. At this point, does anyone know what you are going to get with Simmons? You assume it is the Simmons from a couple of years ago but can you be sure?
If I was the Nets, I would not trade Harden for Simmons or for Smart/RWill. Simmons is too much risk and Smart/RWill is just not enough value. Now, would I trade Smart and RWill for Simmons? In the off season, yes, but only after some thorough physical and mental vetting. I am not so sure I would do that trade right now though. It would be hard to know for sure where Simmons' head is at. Does he even want to be in Boston?
