Might sound like a dumb thing to say, but Tatum fouling out might have been a slight blessing in disguise especially since they won. That's because he'd been playing super heavy minutes lately and was able to play just 36 in Game 4. Keeps those legs a bit fresher going forward
Timelord coming back for good will also help the frontcourt (Theis, Horford) immensely in terms of both impact and minutes.
