Chicago -- Joe Staley's scouting report on Sunday opponent Willie Young: Long arms, quick first step, heavy head.
Wait. Did he say heavy head?
"Like, a bull-rush," Staley explained. "He kind of head-butts you."
The matchup between the 49ers’ veteran left tackle and Young, one of the Chicago Bears' outside linebackers, may be the most compelling part of a game between lowly teams that have combined for three wins this season.
Of Young's three multi-sack games in his seven-year career, two have come against San Francisco, including 1 1/2 in last year's overtime win by the 49ers.
