ORCHARD PARK, N.Y. (AP) - After a slow start to his career in Buffalo, Super Mario has found the next level.

Too bad for the Bills and their fans, it's a little late for a realistic postseason push.

Either way, the high-priced defensive end is starting to give Buffalo a bit of a return on its offseason investment. The Bills have slipped to 4-7, but Williams has posted four sacks in his last four games and leads the team with 8 1/2.

In doing so, he's lifting the play of the entire defensive unit.

The Bills, who welcome the scuffling Jacksonville Jaguars (2-9) to Buffalo on Sunday, have held the opposition to a single offensive touchdown in consecutive weeks after allowing 45 or more points three times in the first five games.
