Why do you want Rob Williams and Al Horford to play together? Why not one or the other - get another skilled offensive threat in there.
.I want to at least see them start some games together. It's interesting because they both pass so well and Al stretches the court.
Horford likely can’t play the 4 anymore. The only time they should see the floor together is if the opposing team plays double bigs as well.
I thought similarly until I remembered that Rob is an excellent perimeter defender. He’s more valuable defending close to the basket and will be utilized in the role primarily, but I have no doubt that he can play well next to Al, as long as Al is shooting well from the outside and is comfortable staying around the perimeter on offense.
The closing lineup will be Horford until Rob mans the role as well as Al.
