The new-look Celtics  may have lost their preseason debut, but the defeat wasn’t entirely discouraging.
In front of the handful of fans not watching the Red Sox , four Celtics reached double figures in the 97-89 loss to the Raptors. Gerald Wallace  (16 points) led the way, followed by Jared Sullinger (14 points, 6 rebounds), Avery Bradley  (12 points) and Kris Humphries (11 points). Of course, other things happened, too.
WHAT WENT WRONG
Tough start: Let’s just say the introduction to the Brad Stevens  Era defense wasn’t pretty. The Raptors grabbed an 8-0 lead, including a pair of uncontested Jonas Valanciunas dunks, and then stretched it to 14-2 against a starting lineup of Avery Bradley, Courtney Lee , Jeff Green , Brandon Bass  and Kris Humphries.
No contest: The Celtics played everyone on the 14-man roster in the first half with the exception of Phil Pressey, and things didn’t get much better defensively. The Raptors shot 59.4 percent from the field and scored 53 points in the opening 24 minutes, including 26 in the paint and 10 on second chances. Somehow, only two of those 53 points came on the fast break, which means the half-court defense wasn’t so good.
Window watching: At halftime, the Celtics had six rebounds. Six. That’s one every four minutes. Their leading rebounder? Six guys with one apiece (four bigs, Gerald Wallace and Avery Bradley). Meanwhile, the Raptors had 22 boards at the break. Valanciunas had a half dozen, or as many as the entire Celtics roster combined. Things improved in the second half, but Toronto still out-rebounded the C’s 46-26 for the game.
WHAT WENT RIGHT
Frontcourt depth: The first three non-guards off the bench — Wallace, Kelly Olynyk and Jared Sullinger — transformed the early 14-2 deficit into a three-point lead late in the first quarter. Olynyk’s passing game was the biggest surprise, as the rookie registered more assists (5) than the rest of his teammates (4) through the first two quarters.
Vitor FAVErani: The mystery behind the Brazilian big man landing in Boston and the unveiling of his mohawk during a glorious Media Day interview  established Faverani as the Honorary Brian Scalabrine  Award winner of this preseason (also known as the Greg Stiemsma  Lifetime Achievement Award), and he didn’t disappoint in his Garden debut. In the 7-footer’s first three minutes, he threw down a breakaway dunk, poached a pair of steals, blocked a shot and set a handful of hard screens. Vitor is still the best.
Over the Hump: For all the off-the-court drama that has plagued Kris Humphries, he quietly showed up early in Boston (in great shape, too), served as a leader to the younger Celtics during pre-camp workouts, earned a starting spot out of camp and then drew a pair of charges early in the first preseason game. In other words, he’s motivated and could win over some Celtics fans this season. In related news, Humphries is in a contract year.
