Sims was charged with two felony counts of second-degree forgery after an incident in which he withdrew $700 from a roommate's checking account. He pleaded guilty and receive a deferred sentence.
Oklahoma State's football program generates more than $41 million but never offered counseling for Simms.
Gundy dismissed him from the team.
"I wasn't playing much and I wasn't helping out the team much so it was easy for them to let me go," Sims said. "It was just all about football. They didn't care about anything I was going through."
Sims is currently a junior at Abilene (Texas) Christian.
"They care a lot here," he said.
Several prominent players were able to avoid being dismissed from the team after pleading guilty to crimes. Jamie Blatnick was a major contributor at defensive end in 2010 despite pleading guilty to a misdemeanor assault and battery charge after he hit a former teammate in the face with a beer bottle. Wide receiver Bo Bowling also played a significant role that year after he pleaded guilty to two drug-possession charges. Chris Collins was a regular at linebacker in 2006 despite later pleading guilty to sexually assaulting a 12-year-old girl. He also played in 2007.
As for Woods, he transferred to Central Oklahoma in 2010 and finally told a counselor about his desire to design video games. He was told the courses he took for three years at Oklahoma State would still require several more years of college. Since he could not afford it, he is pursuing a degree in general studies.
He believes Oklahoma State still owes him money for his pain.
