Jennings' role with Vikings

The notion that the Minnesota Vikings traded Percy Harvin and replaced him with Greg Jennings may be a bit of an oversimplification. True, both are play-making wide receivers, but their skill sets are completely different. The most obvious difference, as 1500ESPN.com's Tom Pelissero notes, is their route-running abilities. Harvin is sloppy in that department, while crisp routes is Jennings' forte.
