Penn State at Iowa
The matchups in the trenches will go a long way toward deciding things when Penn State trvles to Iowa in Week 5.
Penn State offense vs. Iowa defense
• RB Evan Royster can bounce off arm tackles and flashes a strong stiff-arm in space, but he's not a traditional power back who can push the pile between the tackles. He needs a seam to be effective inside, and Penn State's interior offensive line doesn't match up well with Iowa defensive tackles Karl Klug, Christian Ballard and Mike Daniels. Klug plays with excellent leverage and is stout for his 270-pound size, and Ballard and Daniels are quick enough to shoot gaps and disrupt plays in the backfield. Nittany Lions RG Stefen Wisniewski doesn't get good push as a drive-blocker, and LG Johnnie Troutman is vulnerable to quickness because he lunges. C Doug Klopacz and his guards have to use sound footwork on combo blocks, down blocks, block-backs and traps because Hawkeyes defensive coordinator Norm Parker frequently stunted and twisted his tackles against Penn State last year. Any false steps could free a defender to deliver a big hit on Royster, who lost a fumble last week and put the ball on the ground against Iowa last year.
