Chad Kanoff landed his first offer from Vanderbilt a few months ago and since then he's been in touch with the coaching staff to learn more about the program.
The North Hollywood (Calif.) Harvard-Westlake quarterback had enough information to make his commitment on Memorial Day.
Kanoff, who has visited Vanderbilt a number of times, is a 6-foot-4, 200-pound prospect who threw for 2,646 yards with 28 touchdowns and five interceptions in his junior season.
It's a big pickup for Vanderbilt and a major commitment for the three-star quarterback from Southern California.
"It's a great academic school and in the best football conference in the nation," Kanoff said.
"I want to be a part of the biggest turnaround in college football history and Nashville is an awesome city."
San Diego State had also offered Kanoff, who said recently that Purdue, Syracuse and others had been showing interest.
The three-star looked good at the Oakland Elite 11 a couple weekends ago. Over the past few months, Kanoff said he has developed a strong relationship with Vanderbilt quarterbacks coach Ricky Rahne.
The Harvard-Westlake quarterback camped at Vanderbilt last summer and that has now turned into his commitment.
