A University of Arizona benefactor has come up with a retention plan that could help keep men's basketball coach Sean Miller, football coach Rich Rodriguez and vice president and director of athletics Greg Byrne in Tucson for the next eight years.

Arizona also has agreed to contract extensions for Miller, Rodriguez and Byrne. Under conditions of the proposed deals, all three would be under contract through May 31, 2019. The Arizona Board of Regents will vote on the extensions June 6.

Details:

— Rodriguez's current deal expires Nov. 30, 2017. The proposed extension would increase the football coach's annual base salary of $1.33 million to $1.5 million. The salary then would increase $100,000 every June 1 through 2018, when it would reach $1.9 million. Rodriguez also earns $495,000 annually for peripheral duties such as radio and TV appearances. Under the proposed deal, that sum would increase to $500,000.
