Murphy TD Video
2 feet down, butt on ground with clear, complete control and possession of the football = TD. Don't bother with the argument that "Murphy was going to ground while making the catch ... yada, yada, yada." He caught the ball in the air. He possessed the ball in the air. He possessed the ball with 1 foot down. He possessed the ball with 2 feet down. He possessed the ball with his butt on the ground.
The Raiders lost this game for 3 other primary reasons:
(1) The kick coverage unit getting gashed by Sproles which set up short fields and cheap points.
(2) Turnovers which took points off the board (Russell INT) or set SD up with a short field (McFadden fumble).
(3) The defense going soft with the game on the line. Going to zone coverage and playing your LBs too far off the line of scrimmage led to back breaking, game deciding points when it mattered most.
