The 2022-23 campaign will be an important one for Philadelphia 76ers guard Matisse Thybulle, Phoenix Suns forward Cameron Johnson and Boston Celtics forward Grant Williams.

That is because Monday's deadline passed without any of them signing rookie extension deals, per ESPN's Adrian Wojnarowski and Yahoo Sports' Chris Haynes. That means they will all become restricted free agents next offseason and could land noteworthy long-term contracts if they impress during the upcoming season.

Charlotte Hornets forward P.J. Washington and Washington Wizards forward Rui Hachimura are also among those who did not sign a rookie extension deal.

Thybulle, Williams and Johnson all figure to have the opportunity to make an impression while competing for a championship.

Williams' Celtics reached the NBA Finals last season in part because of his solid defense on Giannis Antetokounmpo during the second-round victory over the Milwaukee Bucks and timely outside shooting throughout the playoffs.
