gold star for USAHOF
Brevin Knight would have the career of a journeyman in the NBA, but the first of his nine teams was Cleveland where he was a First Team All-Rookie averaging 9.0 Points per Game.  That year, Knight would lead the NBA in Steals per Game, so there was a lot of hope that this would be the start of greatness.  It wasn't, as he never had theft numbers like that again and he never reached double digits in Points per Game as a Cavalier.  His Assists numbers also did not increase from his 8.2 as a rookie, but his overall average PER as a Cav was 16.2, a decent total.
John Johnson made history as the first Cleveland Cavalier to be named to the All-Star Game, which he did as a rookie in 1970/71.  Repeating his All-Star Game appearance the next season, Johnson would put up a career-high 17.0 Points per Game and overall in his three years in Cleveland he averaged 15.9 Points and 7.1 Rebounds per Game.  While Johnson was a two-time All-Star, he probably wasn't All-Star worthy, but he did represent the city well and was the team's best player in the very early years of the franchise.

Carlos Boozer would turn out to be a nice surprise as the 35th Overall Pick of the 2002 Draft had a nice rookie season averaging an even 10 Points per Game with a 17.0 PER while earning Second Team All-Rookie honors.  Boozer was poised to be the next great Power Forward in the NBA as in his second season he elevated his PER to 20.8 (16th overall) and averaged a double-double with 15.5 Points and 11.4 Rebounds per Game, the latter stat seeing him finish fifth in the league.

Bobby Phills was drafted in the 2nd Round of the Milwaukee Bucks in 1991, but he never made it to the NBA with them.  He would eventually latch on to Cleveland and worked his way into a permanent roster spot with the Cavs where he would be known for his ferocious defensive ability.  Phills (who Michael Jordan once called one of the toughest men to defend him) was a Second Team All-Defensive Selection in 1995/96, and he would average 10.5 Points per Game over his 334 games in Cleveland.

Roy Hinson played his first three years in the NBA with the Cleveland Cavaliers where the former Atlantic 10 Player of the Year would have his best year in the NBA.  That was 1985/86, his third season where he averaged 19.6 Points per Game and a 17.6 PER, both career highs.  In the two seasons before, Hinson finished sixth in Blocks per Game.  The Forward’s overall average in Cleveland showed him average 13.6 Points, 7.2 Rebounds and 1.8 Blocks per Game.
A Gold Medalist for Team U.S.A. in 1976, Phil Hubbard began his professional basketball career with the Detroit Pistons.  The Small Forward would play for the Cleveland Cavaliers for eight years and would peak at 15.8 Points per Game in the 1984/85 season.  Overall in his 469 Games Played for Cleveland, he would average 10.6 Points per Game.

Mo Williams played with LeBron James and was one of the best beneficiaries of being a teammate of one of the greatest basketball players of all-time.

Already an eight-time All-Star before he was traded from Seattle, Wilkens would be named to his ninth All-Star Game as he would average 20.5 Points per Game, the second-highest of his career.  He was second overall in Assists per Game with an 8.2 Average, and he would also have a career-high of 20.3 in PER.  Age would catch up with Wilkens the following year as he dropped to 16.4 Points and 7.1 Assists per Game and his contract would be sold to Portland for what would be his final season as a player.

After a rookie season with the Los Angeles Lakers, Jim Cleamons was traded to Cleveland where he would play for five years and would have three consecutive years where he would average over 10 Points and 5 Assists per Game (1974-75 to 1976-77).  Cleamons was an above-average defensive player, and in 1975/76 he was a Second Team All-NBA Defensive Selection.
Mike Mitchell would play his first three and a half seasons in the NBA for the Cleveland Cavaliers where he was named an All-Star in 1981.  Mitchell played 271 Games for the Cavs where he had his biggest scoring season with a 24.5 PPG, which was good enough for eighth overall.  The scorer would post a 19.3 PPG over his career for Cleveland.

Jim Brewer played his first five and a half seasons in the NBA with the Cleveland Cavaliers where the former Minnesota Golden Gopher (and teammate of future Baseball Hall of Famer, Dave Winfield) and second overall pick of the 1973 Draft would display his defensive prowess. 

Is this rank too low for the “Reign Man”

Shawn Kemp is correctly most identified as a member of the Seattle SuperSonics but he played three seasons with the Cleveland Cavaliers for three seasons where he put up some excellent numbers.

Playing his first four seasons of his career with the Cleveland Cavaliers, Chris Mills would average at least 12 Points per Game in the last three of those four years.  Starting at Small Forward in those three seasons, Mills peaked at 15.1 Points per Game in 1995/96 and was considered stable (though not necessarily spectacular) at both ends of the court.  He would overall average 12.6 Points per Game in his 319 Games as a Cav.

After having a great career at Duke where he was the Naismith Player of the Year in 1989 he was drafted by the Los Angeles Clippers second overall which was a mess of a franchise and Ferry elected to play pro in Italy rather play for L.A.'s red-headed stepchild.  The Clippers traded him to Cleveland, and while Danny Ferry was far from the star he was at Duke he was an excellent role player with a high basketball I.Q. and was a locker room leader. 

Not very much was expected from Clarence “Foots” Walker as he was a 3rd Round Pick from Vincennes University, but he would make the Cavs team as a back-up Point Guard and slowly work his way to becoming their starter in his fourth season with the team.  Walker would play six years for Cleveland and would make history as the first Cavalier to score a triple-double.  

Wesley Person would play five of his ten seasons in the NBA with the Cleveland Cavilers, where he would be his most productive.  Person’s first season (1997/98) with Cleveland would see him jack up the most threes, and lead the NBA in Three-Point Field Goals made or attempted.  It was one of the best years of his career, with career highs in VORP (5.2) and he averaged 13.7 Points per Game, but he regressed the year after and would lose his starting Shooting Guard the year after but would rebound in 2001/02 (his last season in Cleveland) with a PPG of 15.1.  Overall, he averaged 12.0. Points per Game with the Cleveland Cavaliers.
Standing at 6’ 11”, Jim Chones gave up his final year at Marquette to join the New York Nets of the ABA.  He would then play a season with the Carolina Cougars before joining the Cleveland Cavaliers of the NBA in 1974, who had his rights after they traded for it from the Los Angeles Lakers.  Chones put up very consistent numbers in his five seasons in Cleveland; he averaged between 12.9 to 15.8 Points per Game in those years, and in terms of boards his low was 8.4 and high was 10.3, all of which were decent.  In his even 400 Games, Chones posted good averages of 14.3 Points, 9.5 Rebounds and 1.1 Blocks per Game.

When people think of Drew Gooden, they mostly remember him as a journeyman.  That is not an inaccurate statement as the Power Forward played for ten teams over his career, but it was with the Cleveland Cavaliers where he had the longest (and arguably most productive) run of his career.

In terms of overall popularity, especially in the 1970s, Bingo Smith is a top-five selection, and how can anyone named "Bingo" not be?

Ron Harper is best known for winning five NBA Championships, three with the Chicago Bulls and two with the Los Angeles Lakers.  He brought those teams a veteran presence and a high basketball IQ, but this was very different than what he was asked to do when he was with the Cleveland Cavaliers.
