I think the 5th starter question will be decided by how much the Celtics believe Time Lord and Horford can share the court together successfully, vs. how much of that is offseason talk to pretend there isn’t a logjam with the bigs. If it works, then Smart, Brown, Tatum, Horford, TimeLord is the clear starting 5, and free agency is to and veteran depth to the bench. If that’s just spin (as I personally think it is), I think starter #5 is either Fournier or Romeo with Tatum playing the 4, or a PF acquired via the trade marker who makes in the $8-13 million range.
