David Wilson’s eyes grew wider and wider as the questions came at him fast and furious just like the way he runs. Now that Giants running back Andre Brown is out for at least a month with another broken left leg Wilson unquestionably is going to have an increased workload. How will he deal with that given he is not exactly Adonis in shoulder pads? How will he hold up with added carries in short yardage? How will his body withstand the punishment of plunges at the goal line? Finally Wilson had listened to enough worried speculation about him breaking. “I’m not like a vase” he exclaimed. Brown was a big big part of the picture in the Giants ground game with specific packages to utilize his exemplary pass-blocking on third down. He also was going to get a regular turn with the offense perhaps getting one series for every two given to Wilson perhaps more depending on the game and the way both backs were operating. But Brown according to a source will be out 4-6 weeks with the small crack near the plate that was inserted last December when Brown fractured his left fibula. There are no plans for Brown to have surgery and the Giants were awaiting results of yesterday’s MRI exam to determine a time frame for his return. The Giants can put Brown on injured reserve designated for return meaning he would have to miss the first eight weeks of the season. A team can use that designation only one time so the Giants must weigh Brown’s worth against not having that special IR spot if they need it for a star player. Players on the short-term IR do not count against the 53-man roster. Any such move cannot be made until Tuesday. There are recognizable names available at running back but that doesn’t mean it’s an appealing list. A source said Brandon Jacobs is in shape and could be ready “whenever needed.” But the Giants are not expected to make a call to their former punishing running back. Other former Giants D.J. Ware and Kregg Lumpkin are also unemployed as are Cedric Benson Michael Turner Ryan Grant Willis McGahee Tim Hightower Beanie Wells and Joseph Addai.
