Before a preseason game in St. Louis two Octobers ago, Timberwolves coach Flip Saunders sent a message to the opposing locker room via the official scorer who nightly collects starting lineups from each team.
Saunders told the scorer to tell "Thibs" the Wolves would start the game by running a play called "93."
Moments later, Bulls coach Tom Thibodeau received the tip and laughed a laugh that echoed down the corridor.
Sure enough, the Wolves opened by running an isolation play for rookie Andrew Wiggins on the left wing.
Both men knew "93" because fundamental parts of their systems and philosophies were coaching fruit that fell from the same tree: that of career coach Bill Musselman.
Musselman coached three-plus NBA seasons with Cleveland and the Wolves from 1980 through 1991, compiled a .302 winning percentage in those two situations with teams that were undermanned and overmatched. But long after Musselman's death in 2000, those who played for him or coached under him worked on in the NBA, planting the roots in a coaching tree in which Saunders, Thibodeau, Scott Brooks, Sam Mitchell, Tyrone Corbin, Sidney Lowe and Bill's son, Eric, all became head coaches there.
Saunders played for Musselman when he was Gophers coach in the 1970s. Thibodeau received his NBA start when Musselman took a chance on a young assistant coach at Harvard and gave him his first pro job with the expansion Wolves' inaugural team in 1989.
"We never worked together," Thibodeau said of the late Saunders last week, "but I always felt like we were connected through Bill."
