On 49ers and the closing of Revis Island

By Mike Sando

Defensive coordinators can adjust their schemes to cover for deficiencies in the secondary.

Cornerback deficiencies can be easier to mask than, say, a shortage at the offensive skill positions.

The New York Jets' ability to adjust their defense without top cornerback Darrelle Revis will be a storyline to monitor for the San Francisco 49ers this week. The 49ers' road game against the Jets in Week 4 comes as New York begins life without its injured star. Revis suffered a season-ending knee injury against the Miami Dolphins on Sunday.

The injury means Michael Crabtree, Randy Moss, Mario Manningham and the 49ers' other receivers won't have to worry about getting stranded on "Revis Island" this week.

Matt Williamson of Scouts Inc. ranked Revis fifth overall Insider and first among cornerbacks Insider in his player rankings for 2012.

"His anticipation and his ability to jump routes is excellent and enables him to make big plays," Williamson wrote. "Many offensive coordinators will create game plans that work the opposite side of the field to negate his potential game-changing performance."

As the charts from ESPN Stats & Information show, the Jets' opponents have fared considerably better in the passing game when Revis wasn't on the field for New York. Other factors could have affected the totals, but the Jets are obviously weaker without their best defensive player.

Revis played about half the snaps in Week 1 and missed the team's Week 2 game against Pittsburgh. A concussion was to blame.
