No fun team? Cavs reportedly ban players' use of hoverboards

The Cleveland Cavaliers are in full no-nonsense mode.

With LeBron James wanting his teammates to bypass pregame introductions in an attempt to stay focused, the team has put an end to hoverboards at Quicken Loans Arena, according to Cleveland.com.

The one player likely who will be affected most by this is J.R. Smith, who rolled into an NBA Finals game on one of the popular contraptions.

The Cavs have become all business of late, as James and company have refused to leave the court when the opposing team's dancers have performed.
