Reggie Lewis was a late round draft pick in 1987, and the product of Northeastern University played less than ten minutes a game as a rookie, so it surprised some when he would blossom when gaining minutes due to Larry Bird's injury and would have an 18.5 PPG season as a sophomore. Lewis would become the starting Shooting Guard, and in 1991/92 and 1992/93 he averaged just over 20 Points per Game, with the first of those seasons seeing him earning All-Star recognition.
Bailey Howell had already been to five All-Star Games (four with Detroit and one with Baltimore) before he arrived in Boston for the back nine of his career. Howell wasn't putting the same numbers that he did before in Boston, but he was now on a more loaded team, and when you are a teammate of Bill Russell, you didn't have to lead the team in boards. Howell was a strong presence in their NBA Championship wins in 1968 and 1969 and was chosen for his sixth All-Star the year before he won his first title. Howell would average 18 Points and 8.4 Rebounds per Game with a 17.9 PER.
Antoine Walker was a champion at the University of Kentucky, and he would be drafted 6th Overall by Boston in 1996, though the Celtics were no longer the dominant team they used to be. The Power Forward would be Boston's primary offensive weapon, and he would be named an All-Star in his sophomore season when he averaged 22.4 Points per Game. Walker would be a workhorse, and in 2001-02 he would lead the NBA in Minutes Played, and Field Goal Attempts and he would also go to his second All-Star Game. Walker also had help with Paul Pierce, and the tandem took the Celtics to the Eastern Conference Finals that year. He would be with Boston one more season and would be chosen for his third and final All-Star Game.
Tom “Satch” Sanders is one of only three players to appear in eight NBA Finals and win them all. To no surprise, the other two are also Celtics.
