5 Available Players Boston Celtics Must Target

The Boston Celtics have made a number of nice moves this offseason, but still have some remaining roster spots to fill.

With 13 players under guaranteed contract, Boston has only the bi-annual exception ($1.9 million) or minimum contracts to offer incoming players, so their options are limited.

With it looking more and more likely that Michael Pietrus will not be returning, who else could the Celtics pursue on the market?

Here's a look at five remaining players who could all help fill a need in Boston.

5. Ronny Turiaf, C

Turiaf is a tough competitor and hustle player that contending teams just love to have around.  He won a championship with the Miami Heat last season and at times during the playoffs started for them at center.

Adding Turiaf will help make up for the departure of Greg Stiemsma and allow Kevin Garnett to log more minutes at power forward.

The Celtics would likely have to use their bi-annual money, as Turiaf opted out of his deal with the Miami Heat so that he could earn a contract larger than the veteran's minimum.

4. Michael Redd, SG

Once thought to be done in the NBA, Redd enjoyed a rejuvenation with the Phoenix Suns last season while playing in 51 games.

Still a talented long-range shooter, Redd chipped in over eight points a game for the Suns last year and is thought to be a high character guy that would fit in well in a veteran locker room.

Redd could help offset the loss of Ray Allen and would likely only cost the veteran's minimum.

3. Matt Barnes, SF

Nothing about Barnes' game is extremely impressive, but he can help out a team in a number of ways.

A good wing defender, Barnes spent the last two season with the Los Angeles Lakers, starting 16 of the 58 games he played in.

With Jeff Green returning from heart surgery as the primary backup at small forward, Boston could use some insurance at the position.  Barnes could also take over the three-point shooter/wing defender role Pietrus played last season.

2. Nate Robinson, PG/SG

Could we see a Robinson revival in Boston?

The 28-year-old spent parts of the '09-'10 and '10-'11 seasons with Boston before being traded in the Kendrick Perkins deal that brought Jeff Green to the Celtics.

Robinson is perhaps the best guard left of all the free agents, putting up 11.2 points and 4.5 assists for the Golden State Warriors last season.

His addition would mean an upgrade over Keyon Dooling and a dangerous shooting combination with Jason Terry coming off the bench.

1. Kenyon Martin, PF/C

While some may refer to Kevin Garnett as a "fake tough guy," I'm not sure the same can be said about Kenyon Martin.

Adding Martin would bring a new dynamic of toughness to the Celtics bench and would bring an interesting dynamic to practice every day between KG and K-Mart.

Martin can play either power forward or center off the bench and still managed to swat away 1.6 shots per 36 minutes last season, his highest ratio since '01-'02.
