Kevin Durant met with both the Golden State Warriors and Los Angeles Clippers on Friday as he opened his free agency discussions with rival teams.

Durant was "blown away" by the Clippers' presentation, according to sources. Durant met with the Clippers for four hours.

The Clippers are trying to sell Durant on the concept of forming a Big 4 by keeping Chris Paul, Blake Griffin and DeAndre Jordan while signing him.

Durant will meet with the Boston Celtics and San Antonio Spurs on Saturday before a scheduled visit with the Miami Heat on Sunday. Durant met with the Oklahoma City Thunder on Thursday and will also meet with them again after his meetings with other teams are done.
