During the 2014 Eastern Conference Finals, Lance Stephenson and the Pacers learned why you should never give LeBron James and the Heat any more motivation than they already have. Stephenson talked some trash to King James during the series—and the Heat responded by delivering several beatdowns to Indiana. But despite that, it looks like there's a chance that San Antonio might be doing the same thing right now.

Not intentionally, of course. Spurs coach Gregg Popovich would never let anyone on his team act the way that Stephenson acted during the Pacers/Heat series. But someone in San Antonio just put up the billboard that you see above, which features a direct shot at the Heat. And, well, something tells us that it won't go over well with LeBron & Co. There's not a whole lot to it. But it's also not very subtle and should serve as some extra motivation for Miami.

Your move, Heat...
