On the one hand, it makes sense that Brad Stevens is running the kind of schemes that made him successful at Butler and, in turn, helped him land the Celtics job this past offseason. On the other hand, it might come as a surprise to some Celtics fans that their team is employing schemes used by a private mid-major school in Indianapolis that became a Cinderella story when it reached consecutive national championship games in 2010 and 2011. Ever the strategist, Stevens wouldn’t go into much detail about his schemes, but he said the ones he has in place in Boston are “probably very different” from what he was using at Butler.
