New on SI: Video: Why Jimmy Butler Makes Miami Heat a Dangerous Threat

SI's Robin Lundberg breaks down why Jimmy Butler has proven to have the skills and leadership to make the Miami Heat a legit threat heading into this year's NBA playoffs.

Miami Heat star Jimmy Butler took his matchup with bubble standout T.J. Warren personally and shut Warren down in a

Heat win over the Indiana Pacers. Of course this after the two had a heated exchange earlier this season.

Sports Illustrated host Robin Lundberg believes it is that sort of mentality from Butler, along with his ability on the court, that has the Heat as a legitimately dangerous team in the NBA's upcoming Eastern Conference playoffs.
