3. Lloyd Moseby
Lloyd Moseby was picked second overall in the 1978 MLB Draft straight out of high school. With being picked that high and the Blue Jays fresh into the league, Moseby was rushed through the minor leagues and was called up in 1980. In his first three seasons, Moseby really struggled. He put up WRC+ numbers in the 70s which is well below average.
Once Moseby finally adjusted to the big league level, he blossomed. In 1984, he had his best season, slashing .315/.376/.499 with 18 home runs and 81 RBI. He stole 27 bases and won his first and only Silver Slugger Award.
The following season he posted a 2.3 dWAR which was eighth in the American League and was at the time the best defensive season in Jays’ history. It now ranks tied for tenth. He also hit 18 home runs and a league-leading 15 triples that year while tacking on 39 stolen bases.
Moseby blossomed from a disappointing player at the start of his career to a player who could hit, hit for power, play good defense, and be a premier base stealer. Moseby ranks sixth in Jays’ history in bWAR and is the franchise’s stolen bases leader. He also ranks in the top five in games played, runs scored, and hits.
