If Williams can become a situational weapon as early as this year, it's going to be fantastic. How much havoc can we wreak defensively if we have Smart & Williams up in opponents' faces and Horford as the anchor?
Smart/ Brown/ Tatum/ Horford/ Williams as defensive lineup of death? Imagine Williams and Smart guarding everyone baseline to baseline, while Brown and Tatum play the switches and passing lanes and Horford anchors it all.
So many combos, so little time, and of course lineups like the above imply we have two All-Stars on the bench just because we can.
