One of college football’s most anticipated openers will kick off Saturday night in Houston, with No. 13 LSU taking on No. 14 Wisconsin -- two programs that might reside in different conferences, but share similar philosophies about playing mean-spirited, physical football.

Both teams have aspirations of competing in the inaugural College Football Playoff, and Saturday’s outcome might eventually rank among the top determining factors in whether they make it into the four-team field.

With that in mind, let’s take a look at five questions facing the two teams as their matchup approaches.

1. Who gets the most carries?

Those around the LSU program say it looks like it’s only a matter of time before freshman running back Leonard Fournette shows why he was the nation’s No. 1 overall recruit. But will Fournette’s time come in this game? LSU coach Les Miles has praised veterans Terrence Magee and Kenny Hilliard throughout August. The seniors have earned their touches, too, so it will be intriguing to observe how LSU distributes the carries between the vets and the young phenom.

2. How will LSU fare in the passing game?

Wisconsin has plenty of holes to fill on defense, but the one area with a veteran presence is its secondary (and the Badgers were 17th nationally against the pass last season, allowing 202.5 yards per game). That would seem like an advantage against an LSU offense that must replace not only its quarterback, but the only receivers who did much of anything last fall, Odell Beckham and Jarvis Landry.

The Tigers have some super-talented youngsters like freshmen Malachi Dupre and Trey Quinn, but many of the team’s wideouts will be playing their first college games. Keep an eye on whether LSU uses its talented group of tight ends and running backs in the passing game. The tight ends will almost certainly get more looks as pass-catchers in 2014 while the young quarterbacks and receivers settle into their roles.

3. Can either team stop the opponent’s run?

Wisconsin obliterated South Carolina’s run defense for 293 yards in its last outing, a 34-24 loss in the Capital One Bowl. Heisman Trophy contender Melvin Gordon ran 25 times for 143 yards in that game. So it would probably be misguided to assume that LSU’s reconstructed front seven is going to completely shut down a Badgers running game that includes Gordon, Corey Clement and four returning starters on the offensive line.

Likewise, Wisconsin lost its entire starting front seven on defense, so the Badgers will probably have some difficulty against an LSU line that also returns four starters -- particularly since backs like Fournette, Magee and Hilliard will be running behind them.

4. How will Wisconsin look up front on D?

Let’s say this one more time: Wisconsin lost every single starter along the defensive line and at linebacker from one of the nation’s best defenses in 2013. We’re talking about standouts like Big Ten Defensive Player of the Year Chris Borland and defensive linemen Beau Allen and Ethan Hemer who helped Wisconsin finish as the nation’s No. 7 defense overall (305.1 ypg) and No. 5 against the run (102.5).

It’s not like the cupboard is bare, though. ESPN Big Ten blogger Brian Bennett listed sophomore linebacker Vince Biegel as a potential playmaker, and the Badgers have others back like linebackers Marcus Trotter and Derek Landisch and defensive linemen Warren Herring and redshirt freshman Chikwe Obasih who should keep defensive coordinator Dave Aranda’s 3-4 defense clicking.

Asking that many new players to function adequately against a veteran LSU front will be asking a lot, though. Wisconsin’s production along the defensive front might be the determining factor in this game.

5. Who FINISHES at quarterback?

Never mind who starts, who’s going to finish this game at quarterback for either team? That might have a much greater impact on this season than who takes the first snaps for either Wisconsin or LSU.

Miles and Wisconsin’s Gary Andersen have tiptoed around questions asking whether the starting quarterback will be Anthony Jennings or Brandon Harris at LSU or Joel Stave or Tanner McEvoy at Wisconsin. But if this is a close game, their choices on who leads their offenses in the fourth quarter -- and how those players perform in such a situation -- might tell us much more about where these competitions are headed.
