I understand making these comparisons, but do you think Madrigal has the potential to win the Gold Glove multiple times as well as an MVP like Fox did? Do you think Nick can walk 87 times per 162 games or hit 45 career homers like Appling did? Because those are parts of those players skills sets, and part of the high ceilings they enjoyed during peak years.
Yes, both are high batting average/low power players, but both had so many other aspects of their game that made them hall of famers, and Nick hasn’t demonstrated that level of ceiling. I can’t see him ever getting to 5 or 6 or 7 WAR in a single season - can you? I could see him putting up 3-4 consistently, though, if he continues to play at his best.
