First impressions: Training camp, Day 3

NEWPORT, R.I. -- Five quick observations after the Boston Celtics wrapped up their third day of training camp Thursday at the Rodgers Recreation Center on the campus of Salve Regina University:

  • Serious fun: It can't be overstated: The Celtics genuinely seem like they are having a blast together already. For all those concerns about chemistry, camp has been a pleasant mix of seriousness on the court, and hijinks off of it (highlighted by Nate Robinson's budding comedy series on Twitter). In the video embedded at the top of this entry, Robinson runs a suicide in Shaq's size 23 shoes, and all the action stops to watch (and laugh).

  • Big shoes to fill: Robinson joked that he could probably put on his size 10 shoes, then still slide into Shaq's kicks. "[Shaq's shoes] are heavier than bricks, way heavier. They said [Robinson had] 30 seconds [to run the suicide], but I don't think they were counting for real. I think that'd be a good punishment. Guys gotta run in Shaq's shoes if you don't do something right."

  • Not fair for Wafer: Celtics coach Doc Rivers admitted Von Wafer hasn't gotten a fair shot at proving himself yet. "It's been unfair for him, honestly, because he’s kinda been with the third unit with Delonte [West] playing with the second unit. [Wafer] hasn’t had the opportunity to play with the better players. The same thing with Luke [Harangody], the same thing with Semih [Erden]. It's very difficult to show how good they are. Preseason, we’ll see a lot more, then [Wafer will] be in with one of those [first] two teams, and then I think I'll have a better look at him."

  • Austin to Duke? Rivers played coy at first, but admitted reports that his son, Austin, has committed to Duke, are true. "Austin Ainge?" Rivers joked, referencing the son of Celtics president of basketball operations Danny Ainge, who also coaches the team's NBA Development League affiliate in Maine. "I don't think he is... No, [Austin Rivers is] leaning [towards Duke] and most likely he'll commit in the next couple days. But it's not official, yet. I'll wait and let him do it."

  • Something to prove: Every office has a LIFO (last in, first out). That's anything but Delonte West with the Celtics. For the third straight day, West was the last one on the court. The gym was empty and the bus had left, yet he was still shooting buckets Thursday. For more on West, check out this article by colleague Peter May.
