Chris Johnson has found his stride just in time to provide the Tennessee Titans' playoff hopes some real legs. In another sign he's emerging from a two-month slumber, Johnson rushed for 153 yards and two touchdowns to lead the Titans to a 23-17 win over the slumping Buffalo Bills on Sunday. Held to under 100 yards seven times in his first eight games, Johnson now has topped the century mark three times in his last four outings.
