Ten games into the 2013 season and Dolphins wide receiver Mike Wallacehas yet to live up to the five-year, $60 million contract he signed in March. He hasn't come close, really. Heading into Week 12, Wallace has 44 receptions for 534 yards and one touchdown. According to Football Outsiders, he's 81st in total value among NFL wideouts, and ProFootballFocus.com ranks him 105th. In Sunday's win over the Chargers, Wallace had four receptions for 39 yards, 17 of which came on one play. It doesn't look like much on paper, but it was enough to impress Dolphins offensive coordinator Mike Sherman. “I thought Mike had a tremendous ball game," Sherman said, via the Miami Herald. "He ran hard, and he ran his routes very disciplined. He was open on a number of occasion and sometimes it was protection issues and we didn't get him the ball, other times we just didn't get him the ball, but I thought Mike had a tremendous impact in that ball game, because he changed how they played us and allowed us an opportunity to control the game with some runs and what not.” And that aspect of Wallace's game -- sheer speed and the looming threat of a big play -- has often been overlooked this season, primarily because he's been spectacularly unproductive.
