Hays is 28y/o in his prime. He’s averaged >2.5 WAR last three years. He could conceivably do even better this year. 2.5 WAR is an absolute ceiling for Norby/Cowser. You’re significantly underrating Hays. I realize there are some shiny new toys, but there is very little chance he gets outperformed by either or a combination of Cowser & Norby this year.
