There've been a few, but not many. Guys that combined great power, a high batting average, and clutch performances. Lou Gehrig comes to mind (as far as other 1st basemen go).
Don’t forget his clutch defensive play in Game one that saved a run.
Gehrig, despite having his life cut short by a terrible disease, left us with a legacy of humility and gratitude for the same opportunities.
Either gentleman is the mirror opposite of the legions of useless celebs who have everything handed to them and still trash this country.
