gold star for USAHOF
Norman Powell was taken by Milwaukee (who traded him to Toronto) in the 2nd Round in 2015 after a good college career at UCLA.  Powell would earn decent playing time early in his career, mostly playing off of the bench, but was efficient in that role, which was his first four seasons.  "Stormin" Norman was clearly due for more playing time, and he was a nice cog in the puzzle that won the 2019 NBA Championship.

Following the title win, Powell moved into a starting role at Shooting Guard.  Powell, who had never averaged 10 Points per Game in a season, blossomed in the role, improving to 16 PPG, and raising his True Shooting Percentage to over .600.  He was doing even better in 2020-21, averaging 17.7 Points per Game, but the struggling Raptors traded Powell to Portland.
A Toronto Raptor for two years, Venezuelan Greivis Vasquez provided depth off the bench in the Guard position.  He would average 9.5 Points per Game in each of his seasons with the Raps.

48. Dee Brown

Probably best known for winning the 1991 Slam Dunk contest and starting for a spell with Boston, Dee Brown had two and half seasons as a Toronto Raptor.  Brown averaged 10.1 Points per Game in Toronto, which is not that much less than he had as a Celtic.
A member of the inaugural season team for the Raptors, Carlos Rogers would have his most productive year as Toronto turned two.  Rogers finished with 9.8 Points per Game and career high numbers in Steals and Blocks per Game.  He would also have a career high PER of 17.0.
The starting Small Forward for the Raptors in the 1996-97 season, Walt Williams would have a 16.4 Points per Game campaign.  That year, his 5.0 Rebounds per Game season would be the most productive of his career.

36. Jalen Rose

On the surface, this might seem like a very low rank for a player that average over 17 Points per Game in his near 200 game career as a Raptor, and in his lone complete season with the North he averaged 18.5 PPG, a more than respectable tally.  That being said, Rose’s advanced metrics were appalling and he let in far more points than he scored…remember Kobe’s 81?  A 0.5 VORP and sub 15 PER are not good tallies for someone who is supposed to be one of your top guys.
Charles Oakley came to Toronto and provided the toughness and veteran leadership that the young Raptors team needed.  He wasn’t the same player that he was with the New York Knicks but he was the force needed to keep the young team in check and was invaluable in that role.
With the Toronto Raptors for two seasons, seven foot Slovenian, Rasho Nesterovic would become well regarded for his no nonsense style of play.  Nesterovic was not a scoring machine but was adept at rebound and blocking and would put up solid defense.

39. Lou Williams

He only played one season for the Toronto Raptors and never started a game for them but in that year, he averaged 15.5 Points per Game with a very good PER of 19.9.  Williams was rewarded for his accomplishments as the NBA Sixth Man Player of the Year.

42. Tracy Murray

Going from the NBA Champion Houston Rockets to the expansion Toronto Raptors Tracy Murray knew he was going to win less but play a lot more.

44. Cory Joseph

How could Cory Joseph not be loved in Toronto?  He is a Torontonian after all!  After winning the NBA Title with San Antonio, Joseph would become a Raptor and play for his hometown team.  The Guard has been used mostly off of the bench and has done well for Toronto especially in clutch situations.  Joseph was traded after two seasons to Indiana, and he averaged 8.9 Points per Game as a Raptor.

41. Matt Bonner

Before the “Red Rocket” became a fan favorite in San Antonio, he was a Toronto Raptor where he too was a beloved by the Raptors faithful. 

40. Rafer Alston

In terms of traditional metrics, the second season that Rafer Alston had in Toronto was one of the best of his career.  Alston had a career high 14.2 Points per Game and his 6.4 Assists per Game was the second best of his career.  Alston would later become the starting Point Guard in Houston for a few seasons but it was in Canada where he proved he could be a starter.

35. Jamario Moon

This might be our favorite story on this list.
Terrence Ross lived by the three and dies by the three, and Raptors fans watched the streaky Shooting Guard drain many from downtown during his Toronto run.  Ross however was very much a one-dimensional player, which despite the 300 plus games he played in the North, necessitated this ranking.
With two runs with the Toronto Raptors, James Johnson was a popular forward amongst the Toronto faithful.  Johnson is at his best on the defensive side of the ball and would finish 7th in Defensive Box Plus/Minus in the 2011/12 season.  To date, Johnson’s best advanced statistics took place as a Raptor.

34. Keon Clark

Known for his above average wingspan, Keon Clark would have by far his best run in the National Basketball Association as a member of the Toronto Raptors.  Mostly used off of the bench, Clark’s 2001-02 season saw him reach career highs with 11.3 Points and 7.4 Rebounds per Game.  He would also have a solid 17.2 PER as a Raptor.
Andrea Bargnani was not a success as a number one pick.  We all know that right?  However, let’s look at the positive first:
Known as the “Junkyard Dog” Jerome Williams was one of the most popular players that the Toronto Raptors ever had.  Williams was a tenacious player who always gave everything he had on every play.  His best season in the NBA was as a Toronto Raptor where in 2002-03 he averaged 9.7 Points and 9.2 Rebounds per Game. 

28. T.J. Ford

T.J. Ford arrived to Toronto and was essentially given a second chance to be a starting Point Guard.  Eventually, he would share that role with Jose Calderon, but Ford would still have a good stint as a Raptor.  Ford averaged 13.2 Points per Game in Toronto and has his best distribution numbers as a Raptor with a 7.2 Assist per Game Average while playing north of the border.  Notably, T.J. Ford had a PER of 20.3 in his 2007-08 campaign.
