Moore is a solid 6th man SG. He shoots 38% from 3, can handle the ball and is a decent defender. Hill is a low usage 3&D SF. Sure an upgrade at SG would have been nice for the Pel's, but Moore isn't terrible.
Guys this was the first game versus the best 3 point shooting offense in the league. Holiday and the other perimeter guys were clearly confused and the shots didn't fall.
That doesn't make those guys necessarily terrible.
