NBA — After agreeing to a buyout with the Houston Rockets, guard John Wall plans to sign a free-agent deal with the LA Clippers. Wall, who was due $47.4 million from the Rockets after exercising the player option for the final year of his contract, agreed to take $6.5 million less to become a free agent. That is roughly the amount of the taxpayer midlevel exception, which Wall could receive once he is able to negotiate a deal with the Clippers. Sources say the Rockets wanted to reach an agreement with Wall before free agency begins Thursday to maximize his options in selecting his next team.
