You can never have too many guards — just ask Isiah Thomas. Boston will have as many as five guys competing at the point following the Celtics’ acquisition of former Hornets PG Dan Dickau. From the Globe’s Shira Springer :

Celtics executive director of basketball operations Danny Ainge confirmed last night that the team has agreed in principle to a sign-and-trade deal with New Orleans that would land point guard Dan Dickau in Boston with a three-year contract worth an average of $2.5 million per year.

Ainge said some details of the deal still must be negotiated, including what the Celtics will give to the Hornets. New Orleans will receive a trade exception in the process.

As a Celtic, Dickau will join a number of point guards (Delonte West, Marcus Banks, Orien Greene, Will Bynum) expected to compete for the starting job.

Dickau has three years of NBA experience, with three teams: Atlanta, Portland, and New Orleans. As a starter for the Hornets for more than half of last season (46 games), he averaged 13.2 points and 5.2 assists in 31.0 minutes.
