I thought the characterization of Wallace as no longer a "one trick pony", but now with about four tricks was accurate. I don't think he runs the full route tree, at least not well, but he has expanded his repertoire.
Wallace is far from a one trick pony anymore. He has blazing speed so he gets categorized as one, but last year alone 73% of his receptions were on short to mid-range routes. He has a ways to go to be a complete receiver, he has room for improvement as far as route running is concerned, but he's much more than just a speedster now
