Scalabrine, who played under Thibodeau in Boston and Chicago, also compared him to the Patriots coach. “Very similar to Bill Belichick if you ever to go to a Bill Belichick practice,” he said. “Every smallest detail of his practice is talked about. Every pass has to be seamed. Every shot has to be quick and balanced. Every pick-and-roll you have to come off shoulder-to-hip.” At one Bulls practice, Scalabrine lost focus and learned that his history with Thibodeau wouldn’t spare him from wrath. “Thibs laid into me something fierce,” said Scalabrine.
