NBA teams are getting busy early in 2019 free agency, and the Boston Celtics are no exception.

After reportedly agreeing to terms with French center Vincent Poirier on Tuesday, the Celtics now have added three players -- Poirier, point guard Kemba Walker and big man Enes Kanter -- since free agency began Sunday night, and they've also brought free agents Daniel Theis and Brad Wanamaker back.

Those were moves Boston needed to make. Walker fills the point guard void left by Kyrie Irving (Brooklyn Nets) and Terry Rozier (Charlotte Hornets), while Kanter and Poirier are necessary depth pieces after the departures of Al Horford (Philadelphia 76ers) and Aron Baynes (Phoenix Suns).

The Celtics' work still isn't done, as a trade for a rotation player is always possible with C's president of basketball operations Danny Ainge calling the shots.

But less than 48 hours into free agency, Boston's depth chart is starting to take focus. Here's a projected starting five with the current roster as of Tuesday:

PG: Kemba Walker
SG: Jaylen Brown
SF: Jayson Tatum
PF: Gordon Hayward
C: Enes Kanter

And here's a look at the complete depth chart:

SG: Jaylen Brown, Romeo Langford*
