The Celtics have exercised their fourth-year option on former No. 3 overall pick Jayson Tatum, league sources tell Shams Charania of The Athletic (Twitter link). Boston has also picked up its third-year option on 2018 first-rounder Robert Williams, according to Keith Smith of Yahoo Sports (Twitter link).

Both options are for the 2020-21 season, with Tatum’s cap hit ($9,897,120) significantly outweighing Williams’ ($2,029,920). Tatum will now be eligible for a contract extension in 2020 and would be on track for restricted free agency in 2021 if he doesn’t sign a new deal next year. Williams has one more year on his rookie contract in 2021-22 — the C’s will have to make a decision on that option by October 31 next year.

Both Tatum and Williams could take on more responsibilities in 2019-20 after a handful of veterans left the Celtics over the summer. Tatum, in particular, figures to be leaned on more heavily as an offensive play-maker with Kyrie Irving no longer in the mix, as the Celtics hope the 21-year-old can take another leap after an up-and-down performance last season.

Williams, meanwhile, will play a more modest role, but Boston’s frontcourt situation is unsettled now that Al Horford, Aron Baynes, and Marcus Morris are playing for new teams. There could be regular minutes available for the former Texas A&M standout going forward.
