Cobbs attended college at the
University of Arkansas, where he played
football for five years. During his freshman season in 1999, Cobbs set the freshman rushing record at Arkansas (668 yards), but it has since been broken by former Razorback running back
Darren McFadden. Cobbs was named to the SEC All-Freshman team in 1999, and led Arkansas to a 27–6 victory over the
Texas Longhorns in the
2000 Cotton Bowl on New Year's Day in Dallas, Texas. Cobbs was named the Offensive MVP for the game after scoring touchdowns rushing and receiving. He suffered a season ending injury early in the 2000 season, and took a medical redshirt as a sophomore. Cobbs packed on weight over the next two years, ballooning up to over 250 lbs. He never really returned to his freshman prowess until his senior season in 2003, when he slimmed back down to around 220 lbs after working out with the Arkansas track team in the off-season. He was a back up running back in 2001 and 2002, having lost his starting job to
Fred Talley. As a senior, Cobbs led the Razorbacks to a 9–4 mark in 2003, and was named 1st team All-
Southeastern Conference, after rushing for 1,320 yards and 10 touchdowns. Cobbs was also named the Offensive MVP of the
2003 Independence Bowl, leading Arkansas to a 27–14 victory over the
Missouri Tigers, rushing 27 times for 141 yards and one touchdown. He finished his collegiate football career with 3,018 rushing yards, good enough for fifth place in school history. ==Professional career==
