On Wednesday, they both decided to hold off.
"I thought I was ready, but the reality is, I'm not," said Beaver.
Marsh said he too was not ready to make a decision.
Marsh, who's nursing a knee injury, will not be making the trip.
"I won't be going, but they will," said Marsh. "I have the SAT's this weekend."
On Tuesday, their teammate Allen committed to Arizona State. The three make up one of the most prospect-laden teams in the West in the 2012 class, with seven players having BCS offers for the Dons.
Beaver is a four-star, ranked 12th nationally while Marsh is a three-star ranked 21st nationally by Scout.com
