The Raiders love to use man-to-man coverage on defense, and they do it as well as anyone in the league. So naturally, the 49ers spent the run-up to Sunday's game figuring out ways to get Oakland into a zone defense with which they were far less comfortable.
The result was a bunch formation, which produced the play of the game for San Francisco, Michael Crabtree's 32-yard touchdown catch at the end of the third quarter. The Raiders were forced to play zone against that formation and no one picked up Crabtree until the ball was well on its way.
"It's hard to man up when you get into the bunch set," Alex Smith said today. "One of the reasons we did a lot of that is because they play so much man to man, and when you get into the bunch sets it's difficult to do that. It's easy for (defenders) to get picked and rubbed. A lot of times we get zoned off, and that's kind of what happened."
Otherwise, Crabtree mostly was covered by the Raiders top cornerback Nnamdi Asomugha, who had shadowed Arizona receiver Larry Fitzgerald earlier in the season. Asked if he considered it a compliment to be trailed by one of the league's best cover men, Crabtree shrugged. "It didn't really matter about Nnamdi," he said. "I wasn't worried about it. I was just trying to win."
