It shouldn't be too big of a surprise that Kevin Stallings and Matt Painter have similar teams.
Both are Purdue alumni, having played at Purdue under longtime coach Gene Keady. Stallings served as an assistant coach under Keady back in the 1980s. Painter was an assistant at Southern Illinois under Bruce Weber -- another longtime Keady assistant -- before spending a year under Keady himself as coach-in-waiting. In short, both Stallings and Painter are following the same blueprint on how to build a college basketball program.

They're almost mirror images of one another, right down to the similar color schemes.
