The deal will place Anthony in the fontcourt with close friend LeBron James, giving the two lottery picks from 2003 a chance to finally play alongside each other in the second half of their careers. James was drafted first overall in 2003, while Anthony went third.
Anthony, 37, appeared in 69 games with the Trail Blazers last season, averaging 13.4 points and 3.1 rebounds, shooting 41 percent on 3-pointers.
He becomes the latest of an impressive list of Lakers offseason additions, joining guard Russell Westbrook (trade), center Dwight Howard, small forward Trevor Ariza, shooting guards Malik Monk and Wayne Ellington, and forward/guard Kent Bazemore.
The Lakers are coming off a first-roud playoff exit vs. the eventual Western Conference champion Suns, and with James turning 37 before the start of 2022, are looking to add all the help they can to make another run at a title.
