College career

Best received scholarship offers from Arizona, Arizona State, California, Michigan, Notre Dame, Oregon, USC, and Washington among others, before ultimately committing to California in 2006.

2007

As a true freshman in 2007, Best was the primary backup to Justin Forsett. On only 29 carries, Best had 221 rushing yards, and 2 touchdowns. Best also caught 13 passes for 174 yards and a receiving touchdown. Best was selected as the team's Most Valuable Freshman as well as the team's J. Scott Duncan Award (Most Valuable Special Teams Player).

2008

Best quickly got the nation's attention in the season opener against Michigan State on August 30. Best had 111 yards on 24 carries including a touchdown. His breakout game came on September 6 in a 66-3 Cal win against Washington State, having two touchdown runs of 80 and 86 yards, respectively. Best finished the game with exactly 200 yards and 3 rushing touchdowns.

Best struggled the following week against Maryland. This was mostly due to California falling behind early, therefore limiting Best's touches, due to a change in game plan by the Bears. Although he returned to form against Colorado State, he dislocated his elbow and would miss the next game against Arizona State. He returned for the Arizona game, and dashed for a 67 yard score that put the Bears ahead in the second quarter. He would rack up 140 all purpose yards against the Wildcats.

After two more impressive outings against UCLA and Oregon, where he averaged over six yards per carry, Best was held to only 30 yards against the USC Trojans. Following a 201-yard rushing game against the Stanford Cardinal in the 2008 Big Game on 19 carries, Best became the seventh consecutive 1,000 rusher for Cal since Jeff Tedford became head coach in 2002. During the last game of the regular season versus Washington on December 6, Best became the first Cal player to rush for over 300 yards in a game and ended the regular season as the Pac-10's leading rusher, beating out Oregon State's Jacquizz Rodgers.

A 186-yard, two touchdown performance in the 2008 Emerald Bowl earned him Offensive MVP honors for the game. Best finished the 2008 season with 1,580 rushing yards, an 8.1-yard per carry average, and 15 touchdowns.

2009

On January 15, 2009 Best underwent surgery to tighten a ligament that had been injured when he dislocated his left elbow against Colorado State on September 27, 2008. This was followed up by foot surgery on January 23 to relieve irritation that was caused when Best bruised his foot halfway through the 2008 season. He missed spring football practice as a result. Best was named as the most explosive player in college football by Rivals.com in February 2009. In early June Best was able to participate in team summer workouts without pain. Entering his junior year, Best's breakout sophomore year caused early speculation of him being a future Heisman candidate and top running back prospect.

In Cal's season opener against Maryland, Best rushed for 137 yards and had two rushing touchdowns in the Bears' 52-13 victory. On September 12 against Eastern Washington, he rushed for 144 yards and one touchdown, and had one 22 yard receiving touchdown. On September 19 against Minnesota he ran for 131 yards and all of Cal's five touchdowns in the victory, a personal best and a modern school record. He was named Pac-10 Player of the Week and Rivals.com National Player of the Week. However, the next week Best was held to 55 rushing yards and no touchdowns on 16 carries against the Oregon Ducks. The following week he was held to 48 yards on 15 carries against the #7 Trojans, also unable to find the end zone. On October 17, Best recorded both his longest run and longest reception against UCLA in California's 45-26 victory over the Bruins.

Best was injured during the second quarter of Cal's November 7 matchup against Oregon State. In the process of scoring a rushing touchdown, he hurdled a defender into the end zone and was accidentally pushed by a second Oregon State defender in mid-air, causing him to land on the back of his head with his helmet coming off. The play resulted in a concussion for Best. After a 13-minute game delay, Best was taken off the field on a stretcher to the Highland General Hospital in Oakland. This was his second concussion in two weeks, following a mild concussion received the previous week against Arizona State. He was released the next day. and did not play the following week's game against Arizona, although he appeared as an honorary team captain. Best would miss the rest of the regular season. On December 16, head coach Jeff Tedford announced that Best would not play in the 2009 Poinsettia Bowl, stating that "'to get him back in game-ready form I don't feel like that's something that we can get done to have him ready to play.'" Best announced on January 2, 2010 that he would forgo his senior year and enter the NFL draft.

Personal

Best's name is a combination of Jah and the last syllable of his father's name, David. His father is originally from St. Lucia and he has one sister named Laurie who is currently attending California State University, Sacramento.

In January 2014, Best sued the NFL & helmet maker Riddell, claiming the league "was aware of the evidence and the risks associated with repetitive traumatic brain injuries ... but deliberately ignored and actively concealed the information". The lawsuit was dismissed in June 2014.
