Kevin Garnett was one of the best players in the NBA, and he carried the Minnesota Timberwolves for years. But there was only so far he could take them without having any real star power around him.  Garnett grew frustrated, and he was traded to the Boston Celtics, who gave up five players and two number one picks for the former MVP.  The Celtics had also acquired Ray Allen, and along with incumbent Paul Pierce, Boston had a big three that could contend with anyone, and they did so immediately!

Tom Heinsohn would play his entire playing career with the Boston Celtics (1956 to 1965), but that was just the beginning of what he would do with the team.  As a player, he would help Boston win eight titles while being named a Second Team All-NBA Selection at Power Forward for four straight years (1961-64).  He wasn't the team's primary star, but he didn't have to be, as he provided Bill Russell, the perfect frontcourt partner, since he was more adept at scoring than Russell was.  Heinsohn would average 18.6 Points per Game and had three 20 PPG years for Boston while also providing useful boarding metrics with an 8.8 average.

While this ranking might seem high considering that Ed Macauley did not win the NBA Championship with the Boston Celtics, this was a man who would become a Naismith Basketball Hall of Fame inductee primarily from what he did in Boston before they would become the franchise that we all know and (maybe) love.)

Dave Cowens stood at 6'9", which, while it is undoubtedly a tall frame, he played at Center, making him a little undersized for that position in the 1970s.  Cowens made up for that with sheer determination, savvy, and every inch of his body to be one of the most complete players in the game, and this was showcased immediately, as he was the Rookie of the Year in 1970-71.  Cowens would become a two-time NBA Champion with Boston in 1974 and 1976 and was a surprise MVP in 1973 (he was not a First Team All-Pro that year).  An eight-time All-Star, Cowens holds the distinction of being one of the few players in NBA history to lead his team in all five major statistical categories (Points, Rebounds, Assists, Steals, and Blocks) in a season (1977-78).  At the point of his retirement (he would come out of retirement and play with Milwaukee for half a season), he averaged 18.6 points and 14.0 Rebounds per Game.
