What's next?

The loss of Leandro Barbosa is a bit of a blow. Barbosa was starting to flourish in an extended role, further proving that he can still play and answering the call when he asked for more minutes.

Barbosa will be missed, but his injury will not change the Celtics' philosophy. They will still rely on ball movement -- heavily -- and they will still not have a legitimate point guard, which is how things were even before Barbosa went down.

What the Celtics will miss the most about Barbosa is his energy. Barbosa was always good for energy points and being able to score a lot in a short amount of time.

Although his final stat line was not very impressive -- 5.2 points, 43.0% from the floor -- it doesn't go to show how Barbosa could make his presence felt as soon as he checked into the game. If you average his numbers out over 36 minutes per game, Barbosa scored 15.1 points and 4.1 assists.

His aggressive defense will be missed as well. Barbosa's quickness helped him to consistently stay in front of his opponents

So where do the Celtics go from here?

Well, they need to add a guard, but it doesn't necessarily need to be a point guard. The Celtics have been very successful without an actual point guard. If Boston can continue to move the ball at the rate they have been, they'll be O.K.

But they do need a body. Shelvin Mack's name has come up a lot over the course of the day, even back when Rondo went down. He is currently playing for the Maine Red Claws, Boston's D-League affiliate. Mack was a member of the Butler Bulldogs when they made it to the national championship game in 2010 and 2011. He is averaging 17.3 points, 4.5 rebounds and 6.5 assists. In two stints in the NBA this season, he's averaging 2.9 points, 1.2 rebounds and 1.8 assists. On a ten-day contract, Mack may be what the Celtics are looking for for the time being.

As far as other options are concerned, Delonte West isn't one of them. West is with the Dallas Mavericks D-League affiliate, the Texas Legends. However, after signing with the team on January 25th, he has not shown up to any games or practices. According to various sources, West is not being considered by the Celtics.

Other free agent guards include Derek Fisher, Michael Redd, Jonny Flynn, and, yes, even Allen Iverson is still out there. Just saying.
