Always impossible to predict the 1st game, mainly because you don't know the opponent.
Reasons why it could be close:
1) WVU a better team than they've been recently, and they've got talent at QB, wideout and running back. A talented QB, especially one with good mobility, can frustrate any defense.
2) PSU breaking in a new QB and that usually means some jitters, mistakes and turnovers, certainly in the 1st half.
Reasons why it hopefully won't be close:
1) PSU is solid up front on both sides of the LOS and probably will be dominant at some matchups. The combination of athletes and experience at OL is incredibly important and PSU hasn't had that for most of the last 20 years.
2) Franklin and staff actually prepare a game plan for early season games; i.e. there will be explosive plays with some sophistication, and the ability to make adjustments based on what WVA defense is doing.
Remember back to Paterno days, these early season games could be nailbiters because Paterno for whatever reason (arrogance, wanting to teach the team a moral lesson, incompetence?) went into them without any kind of offensive game plan. They would run maybe a half dozen plays all day, totally predictable, and if they couldn't physically dominate, they'd punt a lot, make mediocre defenses look great, and rely on the defense to win a nailbiter in the 4Q.
Franklin doesn't believe in toying with opponents, or creating artificial adversity for his team, and he, more than Paterno, actually believes his rhetoric about the most important game of the season being this week's game. So PSU will be prepared to attack on both sides of the ball, and if they can decide the game in the 1st half, they will.
