PITTSBURGH -- With three key starters sidelined due to injuries, the Jets' depth will be tested against the Steelers. This is the type of game that shines a light on the work of GM Mike Tannenbaum. It will show how much talent they have at the bottom of the roster.

CB Darrelle Revis (concussion), TE Dustin Keller (hamstring) and OLB Bryan Thomas (hamstring) are out, meaning seldom-used players will be inserted into key roles.

Former first-round pick Kyle Wilson will start for Revis, but backups such as Ellis Lankster and Isaiah Trufant will move up in the cornerback pecking order. Rookie S Josh Bush also might be asked to play a role in certain sub packages.

Garrett McIntyre is slated to replace Thomas in the 3-4 base defense, but don't be surprised if they use more 4-3 looks. That, of course, will test the defensive-line depth.

Offensively, second-tier players such as TE Konrad Reuland and TE Dedrick Epps, just re-signed from the Bears' practice squad, will be asked to step up.

The Steelers, who probably will be without S Troy Polamalu (calf) and LB James Harrison (knee), are in the same predicament as the Jets. In the end, it might come down to the team with the best depth. May the best GM win.
