Rajon Rondo  became the only player in NBA history to record 67 assists through four games, leading the Celtics  to a 109-86, wire-to-wire victory over the winless Detroit Pistons . Kevin Garnett  and Paul Pierce  scored 22 and 21 points for the C’s (3-1), respectively, as five Boston players reached double figures.
THREE THINGS THAT WENT RIGHT
1. Taking care of the ball: After averaging 19 turnovers in their first three games, the Celtics committed just two turnovers in the first half and eight for the entire game.
Rajon Rondo and Kevin Garnett had been the C’s biggest culprits, averaging nine giveaways between them through three contests. Last night, though, neither committed a turnover in a total of 69 minutes on the floor.
2. Spread the wealth: The Celtics totaled 33 assists on 42 field goals in the victory. Rondo, of course, led the way with 17 dishes, while Paul Pierce, Ray Allen  and Nate Robinson  each chipped in three dimes.
By contrast, the Pistons managed just 11 assists on 35 field goals for the game. Detroit’s starting point guard, Rodney Stuckey , had just two assists in 38 minutes on the floor.
3. They played the Pistons: Facing little to nothing in the way of defense, the Celtics shot 51 percent from the field, scoring 67 of their 109 points in the paint. KG and Pierce combined to shoot 17-of-25 from the floor (68 percent), getting open look after open look around the basket. Of course, it also helped that the Celtics made all 18 of their free throws on the night.
THREE THINGS THAT WENT WRONG
1. Technical difficulty: While Glen Davis  played well – totaling 10 points and five rebounds in 23 minutes – he picked up a technical midway through the first quarter. Doc Rivers  was noticeably upset, as the C’s are attempting to make a concerted effort not to pick up cheap techs as a result of the new rules.
2. Getting out-rebounded: Rivers has made rebounding a focus for the Celtics early in the season, and they had owned a plus-six margin entering last night’s game. However, the Pistons out-rebounded the Celtics, 38-36. No Celtics reached double digits in rebounds, as KG led the team with six.
3. Bench depth: Big contributions from Big Baby off the bench have become an expectation, and he delivered again. But other than a few bright spots from Semih Erden, the C’s got very little from the rest of their reserves – as Marquis Daniels , Nate Robinson, Von Wafer , Luke Harangody and Erden combined for 19 points in 61 total minutes.
The lack of contribution from the bench led to the Pistons nearly bringing a 20-point lead to single digits – forcing Rivers to bring the starters back in for the majority of the fourth quarter.
