I think the focus needs to be on a big. Right now, our "big" rotation is pretty up in the air:
Under Contract actual bigs:
Under Contract "but":
Morris (kind of a swing)
Ojeleye (still developing)
Yabusele (still developing)
Tatum (I don't see him as a regular big)
So really all we have is Horford and Theis with Morris. I don't think we can count on Ojeleye and Yabusele for regular rotation minutes, certainly not for a playoff run. Horford is a legit starter. Theis and Morris are probably better off the bench. We need a starting level big added. I don't think Tatum is a starting level big. I like Baynes, we could get by with him. Favors may be a good fit but I don't see us having the money to match what he will command.
