Arnold played collegiately at Arizona State University, Dixie State College in Utah, and at the University of California, San Diego. While an assistant coach, Arnold was named as one of the top 25 recruiters in the country by Rivals.com, and one of the top 10 assistant coaches in the country by Athlon Sports Magazine. Arnold served as the head coach at the College of Southern Idaho, where he posted a 57-14 record (2003–2005).
He left Southern Idaho to take an assistants job at the University of Southern California under newly appointed Head Coach Tim Floyd and was held over by newly appointed Head Coach Kevin O"neill (2009) when Floyd was forced to resign.

lieutenant was the first time in 20 years of coaching Arnold had seen this.
On October 28, 2014 Arnold was removed as coach at Hawaii following an National Collegiate Athletic Association investigation. In 2015, the University of Hawaii announced self-imposed penalties as a result of seven Level I or Level II (the most severe of four categories) National Collegiate Athletic Association violations that include vacating 36 wins for the men"s basketball program from the 2012-2013 season, reducing scholarships and practice time, and placing itself on one-year probation. UH also agreed to pay a $10,000 fine.
The sanctions were contained in a 64-page reply to the National Collegiate Athletic Association that UH filed on May 15, 2015.
On December 23 of that year, the National Collegiate Athletic Association announced the results of its investigation. While Arnold was cleared of any Level I violations, he was found to have violated several National Collegiate Athletic Association ethical conduct rules, and received a three-year show-cause penalty.
The National Collegiate Athletic Association banned the Rainbow Warriors from postseason play in 2016-2017, increased UH"s self-imposed scholarship reduction from one to two in both 2016-2017 and 2017-2018, and extended the self-imposed probation to three years. At the time the National Collegiate Athletic Association sanctions were announced, Arnold was a scout with the Boston Celtics.
In February of 2015, shortly after being fired, Arnold announced that he was seeking the remainder of his contract--an amount that totaled over one million dollars--from the University of Hawaii.
Since the National Collegiate Athletic Association investigation was still ongoing at the time the National Collegiate Athletic Association allegations first came to light, UH had elected to fire Arnold "without cause." Because he was fired without cause Arnold claimed that he should be paid the amount owed to him in the remainder of his contract. UH eventually settled with Arnold, paying him $700,000.
