After getting 1,236 yards in 233 carries (5.2-yard average) and 14 touchdowns as a sophomore last season, Hill rushed 226 times for 1,161 yards (5.1 yards per carry) and 13 touchdowns this season.
In Wisconsin's loss in the Champs Sports Bowl, Hill rushed 15 times for 140 yards (9.3 yards per carry), being the lone bright spot of the game for the Badgers.
Hill ends his UW career in third place on Wisconsin's all-time rushing list with 3,996 yards. Along with Ron Dayne, he is one of only two players in Badger history to run for at least 1,000 yards in each of their first three seasons. Hill is also tied for second on UW's all-time touchdowns list with 44 and ranks third in school history with 20 career 100-yard performances.
"I just feel the time is right for me to take the next step in my career," Hill said in a statement. "I would like to thank my teammates, coaches and the Badger fans for the great experience I had during my time at UW."
The Badgers also announced that junior tight end Garrett Graham would return for his senior season. Graham led the Badgers in receptions (40), receiving yards (540) and receiving touchdowns (5) in 2008 despite missing two full games because of injury.
"I know that Garrett is looking forward to completing his time at UW and improving for his senior season and we are thrilled to have him returning," said Bielema.
