Both 2012 draft picks Jared Sullinger and Fab Melo brought their A-game this summer. Meanwhile, former Temple star Dionte Christmas was the surprise player and was arguably the best talent.
According to ESPNBoston.com's Greg Payne, Christmas and the Celtics have reached an agreement after his star-studded summer league play.
There was no question these Celtics were out to prove their worth and surely made strong impressions this offseason.
These are the summer league grades for each player that played in both Las Vegas and Orlando with the team.
Note: JaJuan Johnson, Sean Williams and E'Twaun Moore will not be noted as they have reportedly been dealt to the Houston Rockets. All listed statistics for each player reflect the Vegas games, as they are the most recent ones to be played.
Considering his playing time, Brackins had himself a fine summer league with the Boston Celtics.
He posted solid scoring and rebounding numbers throughout the games. Yet experience should have helped Brackins produce even more effectively. This is a guy who played the last two seasons with the Philadelphia 76ers.
The numbers lift him up to a C+, but it's tough to give too much credit to a guy with two NBA years under his belt.
Larry Owens played with the New Jersey Nets in the 2011-12 season.
Larry Owens, Stephane Lasme and Jonathan Gibson had themselves solid summer leagues with the Celtics.
However, their minutes were so insignificant and scattered that it is difficult to say they earned a specific letter grade based on their performances.
Lasme is known for his impressive shot-blocking and rebounding ability. During the games, Lasme posted 3.2 rebounds and 0.6 blocks in just under 13 minutes per game. The former UMass star was certainly effective when given the chance.
Meanwhile, Owens and Gibson had a difficult time getting going when on the floor. Owens scored in double digits just twice in seven games. Gibson was easily the more productive of the two at 7.8 points in 14.4 minutes per game in Vegas.
These three players posted respectable numbers in the 2012 summer games but didn't play the solid minutes they needed in order to be given a grade.
Jamar Smith's play has been outright effective during the summer league. He can score the lights out and did just that in his mere 23.8 minutes per game in Vegas.
Smith's greatest asset is his range. He was a top-threat in the country from three-point range at Southern Indiana and has been on fire in these games. Smith shot 45 percent from distance in Orlando and just over 32 percent in Vegas.
According to Boston.com's Frank Dell'Apa, the team has agreed to have Smith on the team through this year's training camp. Smith played for BK Prostejov in the Czech Republic last season.
Rest assured, the Celtics took notice of this talent.
Kris Joseph showed bursts of potential throughout the 2012 summer league games. The problem for this young talent was not picking up stats, but sustaining the production.
In the Orlando games, Joseph was posting significantly better rebounding numbers. He boasted 5.8 boards per contest in just over 21 minutes per game. His aggressive play on the boards went downhill in Vegas to say the least.
The Celtics made one heck of a second-round selection by taking Joseph. Make no mistake about it. Yet if he expects to play significant minutes next season, it will take added consistency on the glass.
To put it simply, Dionte Christmas had no mercy for the opposition when he had the rock.
Christmas was as lethal a scoring threat as any both in Vegas and Orlando. In the Vegas games is where this former Temple Owl shined brightest. Christmas shot the ball 47.9 percent from the field and a whopping 45 percent from distance.
Not to mention, he was also a defensive hound on the perimeter. Christmas averaged two steals per game in Vegas as well.
According to ESPNBoston.com's Greg Payne, after the Vegas games the Celtics and Christmas reached an agreement with the guard. His efforts have easily been the most shocking of these summer-league Celtics.
Head coach Doc Rivers has to love what he's seeing from this underrated talent.
The numbers don't deceive here for Jared Sullinger. In fact, there is no question that Sullinger was the most talented player for the Celtics at the 2012 summer games.
His low-post game offensively has been top-notch during these games. The only real knock on the former Ohio State Buckeye here is his one-rebound performance to close out the Vegas trip.
The Celtics struggled mightily in the rebounding department last season. Therefore, putting up consistent rebounding numbers next season will be vital for the Celtics' championship hopes.
