I made my impression on after trade deadline/waived acquisitions on news like these from Celticlife.com. If I'm not misktaken, the C's picked up Michael Finley in the '09-'10 season via this route.
"Make way for the return of Chris Johnson?
Shortly after the trade deadline passed, DH speculated about the Celtics possibly look to re-sign recently waived Portland Center Chris Johnson. A few hours later, ESPN Boston's Chris Forsberg posted a column with some pros and cons on adding CJ.
Johnson spent part of the training camp with the Celtics before the 2010-11 season, then got plucked out of the D-League on a 10-day contract after Boston was thinned up front by the Kendrick Perkins trade at last year's deadline. Johnson appeared in four games for the Green, chipping in six points and five rebounds over 32 minutes of floor time.
Coach Doc Rivers expressed a desire to hold onto him even as his 10-day stint expired, but a need for a backup point guard instead forced the team to sign a bought out Carlos Arroyo. Johnson went on to sign with the Blazers and spent the past calendar year with the team before being released on Thursday.
Would the Celtics be interested in Johnson? There's certainly a value in a 26-year-old with some familiarity of your system, particularly when you're just looking for someone to eat minutes over the next 45 days.
The sexy name out there right now is Chris Kaman (yes I just used sexy in the same sentence with the Caveman), but it's unclear whether he's willing to give up enough millions to convince the league owned Hornets to buy him out. Then even if he is bought out, the Celtics will have to compete with several other teams, most notably the Heat and Spurs.
And I found out that there is a deadline for signing waived players AFTER the trade deadline:
No deal for Heat; focus turns to buyout deadline

PHILADELPHIA—
There are deadlines. And then there are drop-dead deadlines.
So at Thursday's NBA trading deadline, the Miami Heat essentially found themselves in a holding pattern.
But there still is wiggle room for the Heat in terms of roster space and time.
With 14 players under contract, one below the league maximum, the Heat now turn their attention to next Thursday's NBA buyout deadline.
A player who has spent time in the league this season must be waived by March 23 in order to be eligible for another team's playoff roster. He then can be signed any time prior to the final day of the season, similar to the process the Heat used to add Mike Bibby a year ago.
Because of that, what didn't happen around the league Thursday potentially was of greater impact to the Heat than the flurry of moves. Foremost, New Orleans Hornets center Chris Kaman and Boston Celtics center Jermaine O'Neal, each in the final years of their contracts, were not dealt, leaving them as potential Heat targets should buyouts be negotiated with their current teams.
Kaman's situation is somewhat clouded by the NBA running the Hornets, with Commissioner David Stern earlier this season blocking a trade of Chris Paul from New Orleans to the Los Angeles Lakers.
In addition, Marcus Camby, also in the final year of his contract, was dealt Thursday to the Houston Rockets by the Portland Trail Blazers, opening a potential buyout possibility there.
