The NFL at the quarter pole: strange days indeed. Cards and Vikings, a combined 7-1. Saints and Lions, a combined 1-7. Rookie quarterbacks Robert Griffin III and Andrew Luck are plugging away, playing well, but the best rookie of the first quarter of the season is a kicker from Missouri Western. The refs are back, and guess what? They're not perfect. Your NFL receiving leader after four weeks: Brian Hartline, with more yards (455) than Larry Fitzgerald and Michael Crabtree combined (443). And referee No. 99, Tony Corrente? Alive and well, to his own surprise.
