Celtics get the stretch big. Turner can either start over Williams and play next to Horford. If not Turner and Williams play together and Turner becomes the stretch four. Murray gives the Celtics the actually point guard they've been needing. This moves Smart back to being the 6th man or shooting guard if we move Brown to the SF, Tatum to the PF and use Turner at the Center position. These two would give the Celtics multiple different looks, increase the scoring, plus becoming a defensive juggernaut. Having Smart and Murray in the same back court would shut down any backcourt in the league. Then having the best shot blocker in the league Turner with Williams at 7th and Horford at 11th.
