The two-star tailback from Upland (Calif.) High School sees no reason he can't do the same.
"I know I have an opportunity as soon as I get up there to start and play," said Abron, who gave a verbal commitment to Colorado earlier this month.
Stewart, who recently completed his stellar career at CU was Abron's host during an official visit in early December.
"That helped out a lot," he said. "Talking to him, he was telling me about the coaching staff and everything was positive."
With Stewart graduating, the running back position will be wide open next fall. Sophomore-to-be Tony Jones gained some valuable experience this season, but Abron believes he can be in the mix right away.
"That was a big part of my decision," said Abron, who had over 1,700 yards and 34 touchdowns this season. "I feel like I can help the team out in many ways."
Whether or not he starts, Abron is excited about being a Buffalo.
"I loved the campus and the coaches; they were just straightforward," he said. "I just felt like what they are about to do with the program, I just wanted to be a part of it.
"I just know with (offensive coordinator Eric Bieniemy's) knowledge, he can help me out and make me a better player."
Abron is also excited to compete in a crowded backfield that includes Jones, freshman Malcolm Creer, sophomore Josh Ford and two 2012 classmates, Terrence Crowder (Galena Park, Texas) and Davien Payne (Perris, Calif.)
"I'm not worried about it," said Abron, who is also a sprinter on the Upland track team. "There's going to be competition anywhere you go. I'm not worried about that at all. It actually excites me.
"I just feel like I'm a team player first. I just want to win."
Abron's move to Boulder was made easier when high school teammate Marques Mosley, a 2-star receiver, committed to the Buffs last week. His fullback, Christian Powell, is also considering signing with the Buffs.
"There's definitely a possibility that he could join," Abron said of Powell.
Until Abron signs his letter of intent in February, other schools can try to change his mind -- and Washington still talks to him. Abron, however, knows where he's going in 2012.
"I've made up my mind," he said. "It's a relief."
