The Boston Celtics saw plenty of roster overturn in the first offseason under president of basketball operations Brad Stevens.
With a number of new faces on the roster and a new head coach in Ime Udoka, the new-look Celtics are deeper than years past and looking to make some noise in the East.
But with all of these new pieces in place, how is their depth chart and rotation impacted?
The Celtics open their season on the road on Wednesday, Oct. 20 against the New York Knicks.
Depth chart
| Starters | Second | Third | Fourth | |
| PG | Dennis Schroder | Payton Pritchard | Ryan Arcidiacono | |
| SG | Marcus Smart | Josh Richardson | Romeo Langford | Garrison Matthews |
| SF | Jaylen Brown | Aaron Nesmith | Juancho Hernangomez | Sam Hauser |
| PF | Jayson Tatum | Al Horford | Grant Williams | Jabari Parker |
| C | Robert Williams III | Enes Kanter | Bruno Fernando |
Key additions and subtractions
The Celtics selected Frenchman Juhann Begarin with the No. 45 overall pick in the 2021 NBA Draft, but he is expected to be a draft-and-stash player that will remain overseas.
They made a flurry of trades that saw a number of players coming and going, with Kemba Walker, Tristan Thompson and Carsen Edwards making their way out and Al Horford, Josh Richardson, Bruno Fernando and Juancho Hernangomez making their way into Boston.
The Celtics didn't stop with just trades, either. They signed free agent guard Dennis Schroder at a massive discount, in addition to bringing back veteran center Enes Kanter following a strong season with the Portland Trail Blazers.
They had to let Evan Fournier, Semi Ojeleye and Tacko Fall walk, but there is no denying that the Celtics bolstered their rotation and depth chart this offseason.
Positional battles
Under a new head coach, it's nearly impossible to predict what Boston's starting lineup and rotation might look like.
The only guarantee is that Jayson Tatum and Jaylen Brown will be somewhere in the starting lineup. After that, there are a number of different ways Udoka could take his starting lineup and rotation because of the versatility and talent this roster possesses.
Team leader Marcus Smart could get the nod as the starting point guard, but he could also slide to the two in favour of Dennis Schroder. Newly acquired Josh Richardson could also crack the starting lineup as a two guard, but would that mean Smart or Schroder would head to the bench?
Payton Pritchard likely has the reserve point guard spot locked up, but don't be surprised to see Romeo Langford log some minutes as a point-forward-type player, too. With that being said, Aaron Nesmith will also compete for minutes on the wing, although, I expect Nesmith to be firmed into his role as the first wing off the bench.
In the frontcourt, will Udoka play big and go with Tatum at the three, Al Horford at the four and Robert Williams III at the five? Or will Horford and Williams battle things out for the starting center role, with Tatum playing the four?
Enes Kanter will definitely be the backup center, while Grant Williams, Juancho Hernangomez and Bruno Fernando will have to fight it out for the remaining frontcourt minutes.
