As that of any rebuilding team should be, the Celtics roster is made up of non-guaranteed deals, expiring contracts and rookies looking to make a name for themselves.
Ahead are the Celtic players who will be fighting for their respective careers this season.
According to HOOPSWORLD.com, Pressey inked a four-year deal with Boston as an undrafted free agent. While the Celtics are on the hook for the first year, Pressey's next two seasons are non-guaranteed, meaning Boston can cut him with a small cap hit.
After spending three years at Missouri, Pressey brings what the Celtics have lacked for much of Rajon Rondo's tenure with the team—a true backup point guard.
Pressey impressed throughout the Orlando Summer League, averaging 9.4 points and 6.6 assists per game. He started out the week with a scorer's mentality, notching double-digits in each of his first three games. But by week's end, Pressey was focusing more on dishing the ball, handing out 10 assists in both of his final two games.
He'll look to make a name for himself when the season rolls around and will truly be tested when camp starts.
Per HOOPSWORLD.com, Brooks is scheduled to make about $1.2 million this season before the Celtics will have the option of picking up a second season at about $2.2 million.
Over two seasons with the New Jersey/Brooklyn Nets, the shooting guard averaged just over 15 points per 36 minutes, according to Basketball-Reference.com. After adding Joe Johnson, the Nets relied less on Brooks last season, and his minutes dipped from almost 30 minutes per game in 2011-12 to 12.5 minutes last year.
The Celtics have more competition at the 2-guard spot, with Avery Bradley, Courtney Lee and Jordan Crawford all vying for the same position.
Under new head coach Brad Stevens, it's likely Brooks will be given at least a fighting chance to earn a spot in the rotation despite so many shooting guards on the roster.
If by season's end Brooks hasn't shown much growth or at least a willingness to alter his game, Boston can choose not to retain his rights.
Bogans will make just over $5 millions in each of his next three seasons, according to HOOPSWORLD.com. He'll make more money next year than he has in the past four seasons combined, but Bogans' contract is guaranteed for only the first season, meaning Boston can cut the forward while taking a small cap hit after this year.
A necessary contract to make Boston's swap of Pierce and Garnett to Brooklyn work, Bogans has played for nine franchises over his career. In his 11th season, the veteran swingman provides the ability to shoot the three, play solid defense and provide leadership to a young Celtic team.
According to Basketball-Reference.com, Bogans averaged over four points per game while playing less than 20 minutes a night over the last four seasons. If Bogans can continue providing a decent output on the court and a leader's mentality in the locker room, he shouldn't have trouble finding work next season, if Boston decides to save the cap space and cut him.
After a down year in Brooklyn, Humphries approaches the final year of a contract in which he'll earn $12 million, according to HOOPSWORLD.com.
Humphries averaged double-digits in points and rebounds over the last two seasons before dipping to 5.8 points and 5.6 rebounds last year. As a veteran on a youthful roster, Humphries has a chance to restore his standing as a consistent performer and worthy of a significant contract.
