In the 80s it is pretty clear that Ripken was extremely underrated defensively. Everyone just knew a shortstop had to be small, fast and make lots of driving stops. Ripken was bigger, slower, and simply had a strong arm and knew where to best position himself on the field. He took away a lot of hits just by being in the right place and able to throw from his feet
His decline in the 90s does not change how far ahead he was from the average shorstop during his first 10 years
Other than Rodriguez (who will soon be seen as a thirdbaseman for his career) what shortstops have had better careers in the past 100 years?
If most people see him as being light years better than Yount or Larkin or Banks, than he his vastly overrated. From what I have seen most people only have him slightly better, which seems pretty accurate to me
