Navy defense vs. Penn State offense: It will be interesting to see whether the Nittany Lions — who lost top running back Silas Redd to Southern Cal and receiver Justin Brown to Oklahoma after the NCAA sanctions were announced in July — come out running or throwing. So far, in losing to Ohio and Virginia, new coach Bill O'Brien has had Penn State passing more (234.5 yards a game) than running (106.5), but that could change after what the Fighting Irish did to Navy. The Midshipmen need to put more pressure on Nittany Lions quarterback Matt McGloin (46 of 83 for 457 yards, four TDs, one interception) than they did against Notre Dame. Sophomore cornerback Parrish Gaines is coming off his best game at Navy, with 12 tackles and his first interception. Penn State receiver Allen Robinson has caught 19 passes for 186 yards and a touchdown, but its three top tailbacks have averaged less than 3.5 yards over a combined 50 carries. Forcing the Nittany Lions to kick field goals might also work considering that Sam Ficken, who took over when Anthony Fera went to Texas, has missed four of five attempts, including a 42-yarder in the closing seconds against Virginia.
