Brad did an awesome job bringing back Horford in 2021 and he clearly had more to offer in the upcoming years, which ultimately helped big time in 2024.
But honestly, he's 39 years old now and I thought he lost a step last year and looked slower (as did Jrue). Idk if it's also injury, but Horford may be mostly done now. Sure, he can be a role player but even then I don't think he can be a team's 6th or 7th man anymore.
And yeah, him leaving a second time on his own accord, I think it's over. Still love Big Al though.
