Paul Pierce and Kevin Garnett are by anyone's definition, the graybeards of this Boston Celtics team.

And yet as they look to get their season back on track, no Celtics players seem to be carrying more of the load than those two.

At a time when their NBA contemporaries are adapting to a diminished role as bit players, these two continue to take center stage. And their efforts have not been in vain, not with the Celtics riding a four-game winning streak heading into Wednesday's game at Toronto.

Boston's bevy of guards have stepped up in absence of Rajon Rondo (torn right ACL, out for the season). But the play of Garnett and Pierce has been just as important.

"I'm having fun," said Pierce. "I'm playing a game I enjoy playing. My responsibility has always been heavy since I put on a Celtics uniform."

But lately, Pierce has been called upon to not just be the C's best scorer, but also impact the game as a passer and on the boards.

During the four-game winning streak, Pierce has averaged 17.3 points which is a slight dip from his scoring average this season. But his rebounds (9.8) and assists (6.3) during that span are both significantly up, which is exactly what the Celtics want - and need - from the Captain.

As for Garnett, his play is not only appreciated by his teammates but also by fans across the globe which is evident by them voting him in as a starter in the Feb. 17 All-Star game in Houston.

Known for his ability to impact the game in just about every area, he has indeed been Boston's Mr. Everything during their current winning streak.

In the last four games, Garnett has averaged 15.8 points, 8.8 rebounds, three assists, 1.8 steals and 1.5 blocks per game.
