The rumor: The Celtics "prioritize flexibility" with their roster and "probably like the idea of bringing back both" Luke Kornet and Xavier Tillman in free agency, per Adam Himmelsbach of the Boston Globe.
The verdict: The desire to keep both is likely fact, but the reality of doing so might be fiction.
When Kristaps Porziņģis and Al Horford are both available, Boston doesn't have a major need a third center, let alone a fourth. Between Porziņģis' injury history and Horford's age (38), though, there are challenges in keeping them upright.
The Celtics need reliable depth behind them, and ideally, they'd have some variety in that depth, because different matchups demand different skills. Kornet and Tillman delivered that this season, with the former supplying length and interior activity and the latter adding mobility and defensive versatility to the mix. It would be helpful to have both again.
Again, this probably hinges on how the market treats them. A significant offer to either one should be able to lure them out of town, since Boston's roster is already so expensive. Will either elicit that type of attention, though? That's debatable.
