Waller, who got his first offer from Washington last month, is hearing from a number of other schools.
Waller, 6-4, 190, had a solid junior season for the Friars, his first as the fulltime quarterback.
"Last year, getting the experience was important but the offense this year was a major change and we used our best athletes," said Waller.
Waller was 112-for-206 for 1,421 yards and 12 touchdowns to six interceptions. He also ran for 1,233 yards and 13 touchdowns.
"We went more spread this year, so the spread offense is what I'm interested in," said Waller. "I could adapt to a new offensive system though."
Waller camped at the Nike Camp and the San Francisco Elite 11 and plans to do that again this next spring as well as 7on7.
"We did 7on7 with my school, but I'm going to play more 7on7," said Waller.
Waller said his first preference is staying on the West Coast.
"If I can stay on the West Coast, that's what I'll do," said Waller. "I just like it out here."
Academically, Waller has a 3.6 GPA with a handful of AP classes and will take the SAT in the spring.
