Every week, NittanyNation takes a look at five storylines that stand out: What should fans keep an eye on? What's the bigger picture? What might be on display Saturday?

Here are NittanyNation's Week 2 storylines:

1. Former walk-on could start at tailback. It's looking more doubtful that Bill Belton will be able to start Saturday. If he can't go, Derek Day -- an unheralded, 193-pound back -- will take his place. Day came in as a preferred walk-on and earned a scholarship as a special teams player before the 2011 season. Even he didn't think he'd make it this far when he first stepped foot on campus, and a lot could be riding on his legs this weekend.
