New York Jets quarterback MARK SANCHEZ had good moments and bad moments in last night's 24-19 loss to the Pittsburgh Steelers.
--But his NASTIEST moment came in the first quarter, when he got caught on camera wiping a booger on backup quarterback MARK BRUNELL'S chest.

Then on one of the last plays of the game, Steelers quarterback BEN ROETHLISBERGER fell on the football . . . and for some reason, his running back RASHARD MENDENHALL briefly started humping him.
