Panthers rookie running back Christian McCaffrey is no stranger to a heavy workload. Heading into Sunday’s regular-season finale at Atlanta, McCaffrey has a team-high 211 touches. But that pales to his sophomore season at Stanford, when he had 337 rushes alone and set the NCAA record with 3,864 all-purpose yards. So no, McCaffrey says he hasn’t run into the so-called “rookie wall” during the latter stages of a productive, first NFL season. “The year’s gone by pretty fast so far. I feel good. I love coming to work everyday. It’s a good group of guys to be with, so that makes it easy. You don’t really get tired of hanging around these guys,” McCaffrey said Wednesday. “Obviously, physically you can get run down a little bit. But we’ve got a great staff. We do a good job taking care of our bodies. I love playing ball, so it’s fun for me.” McCaffrey, the No. 8 overall pick, has broken seven team records for rookies or running backs, surpassing Kelvin Benjamin last week as the franchise’s rookie receiving leader with his 75th catch.
