I don't this the Harden/Simmons trade is that surprising.

Harden is not getting younger and his contract (extension) can put you in cap hell in a hurry. Plus he was obviously sick of Kemba's bullshit and was not sticking around after the year anyways. Philly got a guy that can definitely get them a ring in the next two years for a pretty young all-star with a very toxic reputation. Philly really has to win in the next two years or they could be in serious trouble tho.
