I would definitely do Turner for Richardson as Turner is starting to hit the brakes on his career. However, I don't think that Harvin would be worth only Titus Young. Sure Titus has taken over Burlesons (SP?) role but I think Harvin is more of a weapon. The upside to this trade would be that Harvin is facing a really tough rest of the season so there is a chance he could be slowed down some. I personally would hold off to see how Titus does this week and then make your decision. Hopefully my rant was somewhat helpful!
