Austin Reaves is now the oldest player on the Lakers roster
Reaves birthday: May 29, 1998 (28 years old)
Players older than Reaves on last year’s roster at the end of the season
All gone or not re-signed
New additions
Still on roster
Lakers still need a few more moves to fill out the roster, could sign an older vet for the minimum and it’s kind of unusual for a roster not to have one. But as of now they seemed to have pointedly targeted players who will be 28 and younger next season.
