The NBA Finals tip off tonight between the Miami Heat and LA Lakers. And while the series is loaded with intriguing storylines, perhaps none is bigger than the drama surrounding LeBron James facing off against his former team. LeBron won two rings in Miami, and with the help of superstars Dwyane Wade and Chris Bosh, seemed destined for years more of dominance. But in 2014, LeBron decided to take his talents back to Cleveland, stunning many within the Heat organization: Heat team president Pat Riley was furious that a team he thought would be a decade-long dynasty went up in smoke. ESPN’s Brian Windhorst takes us inside the complicated relationship between LeBron and Riley...and what it means for one of the most unexpected NBA Championship matchups we’ve seen in years.
