Another twist on Ruth's greatness was written by Bill Jenkinson in 2007. His grandson and my son just graduated high school together in PA and we've had a copy for several years. It's a pretty exhaustive researched book where he makes the case that Ruth would have hit 104 home runs in 1921 playing in today's parks and under current rules. Interesting take, for sure!
