Pro Football Focus is not the be-all-end-all source for in depth info. I personally will not comment in depth on players unless I’ve watched their film, but despite PFF’s arguably flawed grading process, they can be a useful resource. Recently, PFF did a series on the NFL’s best receiver when it comes to running each of the nine routes on a route tree, and Mike Wallace made the cut.
Best slant route runner (min. 10 targeted routes): Mike Wallace, Baltimore Ravens
Mike Wallace left defenders in the dust when running the slant route.
