UNIVERSITY PARK — The fans roared as Anthony Morelli threw darts down the field to wide-open receivers, as tailbacks Rodney Kinlaw and Evan Royster raced across open real estate and as linebackers Dan Connor and Sean Lee brought down ball carriers in the backfield.
  The reasons that allowed them to cheer Saturday were the mostly anonymous brutes up front, who helped Penn State to a 38-7 Homecoming dismantling of No. 19 Wisconsin before an announced 109,754 in Beaver Stadium.
  “They’re growing up,” Penn State coach Joe Paterno said of his Nittany Lions, now 5-2 and 2-2 in Big Ten play. Especially along the offensive and defensive lines.
  The Badgers (5-2, 2-2), traditionally the conference’s biggest and most physical team, turned the ball over three times and had massive and frequent breakdowns in the secondary, but were mostly undone by the Nittany Lions along the line of scrimmage.
  Penn State’s rapidly jelling offensive line helped the Nittany Lions to 221 yards rushing and gave Morelli, who was 16-of-28 for 216 yards, one touchdown and no interceptions, ample time to operate.
  “We knew we could do some things running the ball, and we got that going,” Penn State center A.Q. Shipley said. “And Anthony could open up the passing game a lot because the linebackers were coming up and we could beat them over the top. I think overall, we did a heckuva job.”
  Even as its rash of injuries continued to grow, the Nittany Lions’ defensive line was the driving force in a unit that sacked Wisconsin quarterback Tyler Donovan (16-of-29, 220 yards, two interceptions) five times and held powerful tailback P.J. Hill to 3.9 yards per carry.
  " We definitely look a lot better than Game One. What are we going into now, Game Eight?” said defensive end Maurice Evans, who continued a torrid stretch with two sacks and three tackles for loss. “We’re starting to mature as a D-line.”
  A defensive lineman had a hand — literally — in the first turning point of the game. Defensive end Josh Gaines knocked the ball out of Hill’s hands on the first play from scrimmage and Lee returned the fumble to the Badgers’ 12-yard line. Three plays later, fullback Matt Hahn dove into the end zone from a yard out.
  Completions of 20 and 18 yards from Morelli to receiver Terrell Golden, who had 64 of his 83 receiving yards in the first quarter, set up Kevin Kelly’s 30-yard field goal with 6:51 left to play in the opening period.
  Donovan’s 32-yard completion to freshman wideout Kyle Jefferson fueled a 10-play, 77-yard drive capped by Hill’s 1-yard touchdown run, and Taylor Mehlhaff’s extra point cut Penn State’s lead to 10-7 with 4:05 left in the first.
  The Badgers, who lost their second straight game after winning their previous 14, would get no closer.
  Donovan’s pass to an open David Gilreath bounced off the hands of the freshman and into the hands of Penn State cornerback Lydell Sargeant. Three plays later, Morelli pump-faked and threw a deep pass down the right sideline to Deon Butler, whose diving catch went for a 29-yard touchdown two minutes into the second quarter.
