Here's my top 10:
1. Curt Warner, 1979-82
Warner finished his career as the No. 2 career rusher in Penn State history with 3,398 yards, and scored 24 touchdowns. He led the team in rushing for three straight seasons, during which time the Lions went 31-5 and won three straight bowl games. He holds the team record for most 100-yard games with 18, the last being a 117-yard, two-touchdown performance in the 27-23 Sugar Bowl win over Georgia that gave the Nittany Lions the 1982 national championship. He was inducted into the College Football Hall of Fame in 2009.
In just two seasons, Barkley already is ranked 12th on the program's all-time rushing list with 2,572 yards and holds the fifth-best single-season total of 1,496 yards, set last year. His 1,972 all-purpose yards over the same period rank second. He scored 22 touchdowns last season, third most in school history, and his 30 points (five touchdowns) against Pittsburgh tied him for fourth on the all-time list. He also has two of the longest runs in program history – 81 yards at Purdue and 79 yards in the Rose Bowl against USC.
3. John Cappelletti, 1972-73
The Upper Darby product enjoyed a historic season in 1973, when he won the Heisman Trophy and led the Nittany Lions to a 12-0 record. He rushed for 1,522 yards – fourth most in school history – and set a program record for carries in a season (286) and a game (41). He rushed for more than 200 yards in three straight games in the final month of the season, including a career-best 220 against North Carolina State. He was elected to the College Football Hall of Fame in 1993.
4. Lenny Moore, 1953-55
Moore, often praised by Joe Paterno as the greatest football player he ever saw, became Penn State's first 1,000-yard rusher in 1954 (1,082 yards) and led the team in rushing for three straight years. He ranks 14th on the school's all-time rushing list with 2,380 yards. He also starred as a defensive back and a return man, and he played 12 years in the NFL with the Baltimore Colts and earned a place in the Pro Football Hall of Fame.
5. Lydell Mitchell, 1969-71
Mitchell, of Salem, N.J., scored more rushing touchdowns (38) and total touchdowns (41) than anyone in school history, and his 26 TDs in 1971 are the most in one season. His 1,567 yards rushing in 1971 remained a school record for more than 30 years. He is eighth on the career rushing list with 2,934 yards.

Carter put together a record nine 100-yard games, finished fourth in the nation in rushing, and scored 23 rush touchdowns in helping lead Penn State to an undefeated season in 1994. His 1,539 yards that year are third all-time and he placed second in the Heisman Trophy balloting. His 7.2 yards per carry in his career is the highest mark in program history. He gave up his senior year to enter the NFL draft, and Cincinnati took him as the top overall pick, making him the first Penn State player to go No. 1.
8. Blair Thomas, 1985-87, 1989
