Joe McKnight said Thursday that he was leaning toward returning to USC for his senior season. "I feel like right now is not the right time to drop everything and leave," said McKnight, a junior. "I feel like I'm not ready for it. "So I just need one more year to get everything straight and get in line." With rumblings that 2011 rookie signing bonuses could be affected by NFL labor negotiations, an increased number of juniors and third-year sophomores throughout college football are expected to consider making themselves available for the 2010 draft. McKnight said, "I want that Heisman Trophy, that's one of the reasons I'm coming back."
