Josh Rosen’s command of UCLA offense impresses Jake Plummer

Josh Rosen’s career debut as UCLA’s starting quarterback left a few mouths agape at the Rose Bowl this past Saturday. A few chins might have even scraped the floor.

Count Jake Plummer among those with at least a raised eyebrow. The former All-American and Pro Bowler now works as a Pac-12 Networks analyst, and offered some of his thoughts on the freshman’s 351-yard, three-touchdown performance in a 34-16 win over Virginia.

“The command of the offense is what really surprised me,” Plummer said. “For a true freshman to come in and have that good of a command of the offense — you watched him go through reads, to step into his throws. He threw with confidence. His location was really, for a freshman, amazing. …

“A couple of times, I saw him throw his guys open. That’s something you learn to do as a quarterback as you get around stiffer competition.”

Plummer also warned not to be get too carried away in praising the freshman, echoing what UCLA head coach Jim Mora has said for at least the past week.

The hype may be difficult to control: According to online sportsbook Bovada, Rosen now has a 14-to-1 shot at winning the Heisman Trophy, way up from the 40-to-1 odds he received a week ago.
