6. Devon White
Devon White was never awfully impressive at the plate. In his five seasons in Toronto, he only raised his WRC+ over 100 just twice, with his best offensive season coming in 1991. That season, he had a 119 WRC+ while hitting 40 doubles, 10 triples, 17 home runs, and stole 33 bases.
While he was an average to the below-average hitter, he was one of the best defensive players in Blue Jays history. His 1992 season saw him put up a franchise-record 3.9 defensive WAR, which was 1.4 more than second-place Cal Ripken Jr. in the American League that season.
White had three straight seasons of over 5.0 fWAR. His 17.7 fWAR from 1991-1993 ranked fourth in the AL and the only outfielder ahead of him was Ken Griffey Jr.
White being that productive as a player while not doing much at the plate in his time in Toronto speaks volumes of just how good he was in the outfield defensively. He won Gold Gloves in each of the five seasons he played in Toronto and was a key piece of the two World Series championship teams, leading off the famed WAMCO lineup.
