The 2012 Celtics were decimated by injuries. The 2013 Celtics are going to be the league's deepest team.
Considering this: Most teams go five or six deep with either solid NBA-caliber players or rookies that they expect to contribute. The best teams usually have seven or eight of those guys. By my count, Boston currently has 10, and that number goes up to 11 if Mickael Pietrus re-signs.
They go two deep at every position. One of the best 1s in the league, Rajon Rondo, is backed up by one of the league's best sixth men, Jason Terry.
One of the league's best defensive 2s (Avery Bradley) will split time with another of the league's best defensive 2s. (Courtney Lee).
Hall of Famer Paul Pierce will man the 3, backed up by the new $36 million man Jeff Green. As a point of reference, no player on Charlotte's entire roster is owed that much, and Boston is so deep that it is giving it to its seventh man.
Boston's front line is just as deep. Brandon Bass is back to play at the 4 and will be relieved by Jared Sullinger, one of my favorite players in the entire draft. I don't care what injury issues he has, if you can take a guy at No. 21 when he would have gone in the top-three a year earlier, it's a great move.
Kevin Garnett revitalized his career at the 5 last year. He's backed up by perhaps the only question mark in Boston's second unit, Fab Melo. Melo is a fantastic defender, but he was held out of the NCAA tournament because of academic issues.
Last I checked, NBA players don't need to know calculus. The Celtics should have no problem keeping him in line.
That isn't even including guys like Pietrus and the newly re-signed Keyon Dooling and Chris Wilcox. If the Celtics go into the playoffs with everyone healthy, they'll have 13 legitimate rotation-caliber players.
Not to keep piling on Charlotte (they do a pretty good job of that themselves), but I'm fairly certain Boston's second unit could beat the Bobcats in a seven-game series by themselves. In fact, I'm fairly certain that that series would go no more than five games.
Ray Allen may be gone, but the Celtics have nothing to worry about. They are absolutely loaded top to bottom. They may not be the best team in the league, but they are by far the deepest.
