Technically, the NBA free agency period was scheduled to open at 6 p.m. Eastern time on Monday. In actuality, it has been rolling along. LeBron James has already opted in to a $52.6 million deal with the Los Angeles Lakers for this coming season, the Houston Rockets have traded for Kevin Durant — not a free agency move, obviously — and the Los Angeles Clippers saw James Harden decline his option in return for a new deal and a raise.
