Five storylines: Idaho vs. LSU

BATON ROUGE, La. -- Sure, it's supposed to be a blowout: LSU, ranked No. 3 in the nation and looking a lot like a No. 1 last week in a 41-3 win against Washington, vs. Idaho, 0-2 and coming off a 2-10 season. LSU, the team with arguably the most defensive talent in college football vs. Idaho, the team that needed more than seven quarters to score its first touchdown this season. So what is there to watch for this weekend?

1. Let it fly?

LSU quarterback Zach Mettenberger went 12-for-18 for 195 yards and a touchdown against Washington and looked good enough for head coach Les Miles to come under fire for not using him enough. Will the Tigers take to the air or wait for a game where they need to throw (like Alabama)?

2. Committee chairman

LSU's running game has been led by Alfred Blue, who has back-to-back 100-yard games to start the season. Will he continue to hold off hard-charging Spencer Ware and the rest of the talented backs to be the main guy in the Tigers' backfield?

3. Let it fly, Pt. 2

Dominique Blackman signed with Washington coming out of high school, then after stops in junior college and Old Dominion, found a home at Idaho, where he completed 30 of 37 passes for 352 yards in his Vandals debut in a 21-13 loss last week to Bowling Green. Can Idaho protect him enough for an encore performance?

4. Running in place?

Idaho's running game has been non-existent with Arizona State transfer Ryan Bass (76 yards on 23 carries) off to a slow start. Can the Vandals establish enough of a running game to at least keep the Tigers vaunted defense from pinning its ears back to get after Blackman?

5. Streakers

LSU will look to be the first team in FBS history to win 40 straight non-conference, regular-season games and will also look for the first 20-game home-field winning streak in the history of venerable Tiger Stadium.
