Have the Celtics finally (it's been a long long time) found a backup point guard in Terrence Williams?

In the "New Big 3" era... or is it the Kevin Garnett era now?  What are we calling it at this point?  In the last 6 seasons since the Celtics have been good again, they have never really had a backup point guard.  They've gone through a list of shooting guards who've filled in as ball handlers; Eddie House, Delonte West, Nate Robinson, Keyon Dooling, Leandro Barbosa, and Jason Terry to name a few (I'm leaving off Sam Cassell, Stephon Marbury, and Carlos Arroyo, although they did all manage to have a cup of coffee with Boston as the last stop at the end of their careers).

The recent emergence of Terrence Williams could give the C's their first legitimate 2nd string point guard in years.  ESPN Boston's Chris Forsberg wrote a piece on Williams last night, and shared some good quotes from the former Louisville Cardinal:
"I never really had a style of play until I came here. Then I got defined in a role. I definitely accept my role here of finding guys and being aggressive at certain times when I need to."

In William's first 11 games in Boston he was mostly an afterthought on the end of the bench, putting up just 2.4 points and 1.1 assists in 8 minutes per game.  But, over the last 7 contests his role has dramatically increased; in that span he's averaging 6 points, 2 assists, and a steal in 18 MPG.  Forsberg also notes Williams' impressive assist to turnover ratio of 3.5 (by comparison Rajon Rondo's is 3.0 for his career) during that stretch.  You can't help but like the guy's attitude as well.  In regards to dislocating his finger on Wednesday night Williams said:
"You've got to cut my hand off for me to actually say I'm not going to play basketball. If I've got to tape my whole finger with all the electric tape you can find, I'm still going to try to play. It's not going to change anything. It's not like I need to shoot 15 shots. I can pass still with two hands or my left hand."
