Zach Zwinak, Daimion StaffordBruce Thorson/US PRESSWIREZach Zwinak was buried on Penn State's depth chart this summer, and now he's the Nittany Lions' best running back.

NittanyNation asked several players for their opinions and also looked at the tape to find Penn State's five most improved players since Week 1:

1. RB Zach Zwinak
He entered Week 1 as a player vying to become the fourth option at tailback: Bill Belton, Derek Day and Michael Zordich were on pace to get more playing time. But as injuries piled up, Zwinak made the most of his limited opportunities and quickly became Penn State's top tailback. He's rushed for at least 90 yards in five of the last seven contests. And in the last two games, he topped 130 yards. He's almost never tackled in the backfield and he even flashed some surprising speed against the Cornhuskers. Zwinak didn't just rise to become the top tailback on this offense. He's one of the team's best players.
