Pre-agency has officially started.

It’s been rumored all week, but with twenty-four hours left until the official start of free agency, it sounds like the Celtics have finally got their man:

With the impending departures of most notable Kyrie Irving and Al Horford, the Celtics have opened up enough cap space to sign Kemba Walker outright with a four-year max. Per Stadium’s Jeff Goodman, Walker chose Boston for “chance to go deep in playoffs — and play with talented guys like Tatum, Hayward and Jaylen Brown.”
