California's true freshman running back Jahvid Best has been highly impressive during the team's preseason practices. "He's special," Cal coach Jeff Tedford said. Best has not played a single down of college football, will not be the starting tailback for the Bears this season and probably won't even begin the season as the backup. Tedford describes Cal's depth chart at the running back position as "Justin Forsett and the rest of them," with redshirt freshman James Montgomery the likely backup to Forsett and another true freshman, Shane Vereen, in the mix for immediate playing time as well. Best has drawn comparisons to Reggie Bush. "You can't put a leash on him," Tedford said. "He does have great instinct, and when he reverses field, it could be a big, big play."
