I completely disagree with your assessment. If you look at their respective lifetime stats, Smith had a higher fielding pct. (.978 vs. .971), and even though he played in 333 more games at shortstop, he had 579 more putouts, 1781 more assists, 30 less errors, and was involved in 300 more double plays. And yes, Smith's per game averages is superior to Concepcion in each of these categories.
Smith got to more balls, made more plays, and made the spectacular plays. No question of his credentials. Not so for Dave Concepcion. Even comparing offensive numbers, Smith is only bested in home runs and rbi's.

I see two pretty equal players - one with more speed and the other with better power. Are you trying to say that on defense ALONE, one is a first-ballot Hall of Famer and the other doesn't get into the Hall at all? BTW, Concepcion won five Gold Gloves himself, so he was no slouch on defense.
