Doc Rivers has faced the Cleveland Cavaliers and Miami Heat with LeBron James as a head coach, as well as twice meeting Kobe Bryant in the NBA Finals.

However, the Los Angeles Clippers' coach said he believes this first-round series against the San Antonio Spurs is his most difficult.

“This is the hardest one by far,” Rivers said.

Both the Clippers and Spurs are tied at 3-3 with Game 7 in Los Angeles on Saturday.

“This series, in some way, should go seven,” Rivers said. “It's almost like it's right; that's what should happen in this series. And it is.”
