The thinking in signing Arroyo is to give the Celts some added depth behind oft-injured reserve Delonte West, who is currently out with a sprained ankle.
Arroyo was, of course, waived by the Miami Heat earlier this week to make room for Mike Bibby. Arroyo was productive for the Heat, but not quite the offensive threat they were interested in, especially as their starter. So the Celtics get a quality backup point guard for the stretch run.
Center Chris Johnson, who was with the Celtics on a 10-day contract, was informed he wouldn't be given a second such deal. The Celtics were interested in a number of players in the buyout market, but hung back a bit, not opting to go for added depth inside.
The Celtics are banking on both O'Neals -- Shaquille and Jermaine -- to regain their health and contribute heading into the postseason. They used the last roster spot on Arroyo, thinking they would be fine on the inside with what they had. Obviously Danny Ainge figured depth behind Rajon Rondo was a more pressing matter.
Pending a physical, Arroyo could join the team as early as Sunday in Milwaukee.
