Mendenhall has talent, but he hasn't shown enough against NFL competition to earn any PT.He had a poor camp and didn't show much against the ones in pre-season. I've said it repetitively he runs with poor pad level which doesn't allow him to generate the power a guy his size should and also results in poor ball security. He was indecisive and only gained yardage when an obvious hole was blocked for him. His feet were slow and he didn't make anybody miss.These should be correctable flaws, but Tomlin isn't giving him reps based on his draft status alone.If nothing has changed from pre-season, he would be more of a liability than assest on the field at this point.He's very young and has time, but is far more of a project than I ever thought he would be.
