With arguably the most grueling stretch of their post-All-Star schedule now behind them, the Boston Celtics can adjust their focus to the final 25 games of the regular season. But with a little less than one-third of the 2012-13 campaign remaining, there's still plenty to sort out while ramping up for another playoff push:

FINALIZING THE ROSTER

There's still a chance the Celtics' roster as it currently stands won't be the one we see when the playoffs begin. Keep an eye on March 1. Not only is it the day Terrence Williams' current 10-day contract expires, but it's the deadline for players put on waivers to be eligible for another team's playoff roster (the Celtics don't have to sign a player by that point, but anyone waived after that point simply isn't playoff eligible). Boston is set to sign former Charlotte big man D.J. White to a 10-day deal (he'll likely make his debut against the Warriors on Friday), but the Celtics still have one roster spot open. The C's likely would fill that spot with another insurance big man, although the list of potential buyout candidates isn't swimming with frontcourt help.

If Boston is determined to add a final body and doesn't go the D-League route, it could consider Lou Amundson, who was released by the Timberwolves earlier this month. Amundson isn't an eye-opening prospect, but he does have playoff experience and he'd be good for an extra measure of toughness on the glass (his career defensive rebounding rate is better than that of Brandon Bass). Beyond that, the Celtics will have to make decisions on Williams and White for the remainder of the season. Each player can run through two 10-day contracts before the Celtics have to decide to keep him for the rest of the season or let him walk.

REST VS. RECORD

Ever since Kevin Garnett came to Boston, this has emerged as the proverbial end-of-season debate. How does coach Doc Rivers balance fighting for a higher playoff seed versus giving his veterans (and best players) the necessary time off to be rested for the playoff push? Rivers has been pretty transparent with his philosophy, which is that he doesn't have a clear-cut answer. There's no simple solution to this problem, particularly when you're dealing with veterans such as 36-year-old Garnett and 35-year-old Paul Pierce, who don't always agree that rest is in their best interest (although Garnett did oblige when he was asked to sit against the Phoenix Suns on Friday).

The thing about these Celtics is that they can't ever truly be counted out, no matter what type of adversity they're forced to endure. Whether it's losing key players to season-ending injuries or battling general inconsistency, Boston always seems to bounce back to life just when it looks like it should be pushed out of the picture.
