BACKCOURT: Bradley is an elite defender who assumed the point guard spot when Rondo went down. He played well at times, but he's not a natural point, nor is he a natural on the offensive side. Bradley shot 40 percent from the field and 31 percent from long range.
Lee averaged a career-low 7.8 ppg last season. He did shoot 46 percent from the field and 37 percent from long range.
BENCH: Wallace was an integral part of the Brooklyn Nets success last season. He will probably see more minutes than any other bench player, especially if the Celtics want to go small with Green at the big forward and Bass at center. Wallace still has something left in the tank, despite a nine-season low of 7.7 ppg in 2012-13. He was the fifth option with the Nets.
Humphries also came from Brooklyn, where he fell out of both Avery Johnson's and P.J. Carlesimo's rotation. He is actually a pretty proficient rebounder and average scorer. As a bench guy, Humphries isn't going to kill you.
Brooks had an awesome rookie season in 2011-12, averaging 12.6 ppg. He tumbled significantly last season, only scoring 5.4 ppg. A change of scenery will do Brooks well.
Jared Sullinger cracked the Celtics' starting lineup last season before his troublesome back injury ended his rookie campaign. He has a history of injury problems and Sullinger was arrested on domestic assault charges over the summer.
COACHING: Stevens is one of the brightest minds in basketball, but the question begs, can a college coach have success in the NBA? History doesn't seem to think so, but Stevens has a decent chance.
First, he's only 37 years old and the youngest coach in the league. He can relate to a young roster. Plus, according to reports, Stevens received a six- year contract, so Ainge has invested in Stevens as his coach during the future turbulence.
Stevens is pro statistical analysis and all about the team, not individual play. Every coach is probably like that, but Stevens is also anti self- promotion.
OUTLOOK: The playoffs are a dream for this Celtics roster. Yes, the Eastern Conference is top-heavy, but without Rondo, who may not be back until December, this Boston team is slender on talent.
With Rondo, the C's could actually be something of a surprise. Olynyk looked good in the summer league, Green is a legit scorer and Wallace, Humphries, Brooks, Lee and Bradley are all decent hands.
Rondo is an elite point guard who sometimes butted heads with the likes of Pierce, Garnett or Ray Allen. How will he handle being the man on the Celtics, albeit the man in the middle of a massive rebuild? Could go either way which may make Rondo expendable at the deadline. He has one year left after this one at $12.9 million.
Ainge has a plan. Stevens is his guy. Ainge got a ton of first-rounders in exchange for Rivers, Pierce and Garnett, so they can rebuild over time. (Which will be necessary since Wallace has three more years left on his deal.)
This season will be the first step...just not one toward the postseason.
