Riley was offered the job prior to Price being hired. The UCLA job was also open at the time, and he had thrown his hat into that ring because it was said that his wife resided in Solano Beach, California and would not leave there regardless of where he went. When he asked Mal to wait until UCLA had made their decision, Mal refused and turned to Price. UCLA hired Karl Dorrell and Riley went back to Oregon State.
To my knowledge Riley's wife was good to her word and still resides in Solano Beach. Doubt if she went to Corvallis or Lincoln.
