I would lean toward at least Yount, Molitor, and Uecker, but there's always a fatal flaw in these Mount Rushmore conversations surrounding proportions. Certainly there are 4 presidents on the face of the rock, but Gutzon Borglum only had to pick out of 29 options. A full 14% of all qualified presidents are on Mount Rushmore. The Brewers have had 1,000+ players, 4 ownership groups, and well 1 radio announcer which leaves room for over 140 faces.
