Thad Lewis completed one pass for a first down even as a blitzing linebacker knocked his helmet off and sent it skittering upfield. The hit drew a flag and left Lewis sprawled on the turf, but the Buffalo Bills' young quarterback leaped to his feet screaming and punching the air to celebrate the gain. Lewis' resilience proved infectious Sunday. The Bills blew an early 14-point lead, then rallied to kick the winning field goal with 33 seconds left and beat the Miami Dolphins 23-21.
