What’s up with Marvin? One of the all-time greatest receivers in NFL history is having issues. It began early last year when he was hurt in the Denver game. He missed most of the season with a knee injury, then came back for the playoff game and promptly fumbled in the red zone on the way to a loss to San Diego. Then, he had off-season knee surgery, a procedure that Hall of Famer Jerry Rice says he had and set him back a year and a half. The off the field issue with the shooting in Philadelphia where his gun was used is still not cleared up. He did look strong in training camp, but has not been close to the receiver he is. So many dropped balls, wrong routes, miscommunication with Manning, and what is even more alarming, an apparent lack of effort at times. Passes we’re used to seeing him dive for are dropping near him on plays he could make. One pass that he dropped near the Steeler goal line Sunday found him getting up slowly after what may have been a knee to the head. They announced in the press box he suffered a concussion, but was back on the next series. Afterwards, Tony Dungy says that injury report didn’t come from him, but Marvin rarely speaks to the media, so we will never know. The mysterious Marvin has become a question mark.
