Danny hinted about grabbing bigs in the free agency. And from what I saw in Grant, he's really strong and smart. Those traits are severely underrated by the scouts. Williams will provide physicality that our interior lacked.
As for Carsen Edwards, you couldn't be more excited about a guard that can shoot deep outside. He can also run the offense, unlike Rozier. For a 6'1" guard, he have elite explosiveness and not a total liability on defense and can play off the ball.
