I think one thing that nebrasketball has going for in it with the roster as currently constructed (knowing that it will fill out a bit more) is the team is pretty long as it is. Worster is 6'4", Williams is 6'6", Gary is 6'6", Griffiths is 6'8". I think there's a world where they add Meah and can put together a really solid defense/rebounding team just because they have good size across 5 positions even if the person who plays the 4 is a little undersized or a little slow.
In my view, the guy they need is another 4/5 type who can play out whether that is because they're a plus 3 pt shooter or because they are a threat to put the ball on the deck and get to the rim like Walker. Milicic was that guy and maybe another is out there. Obviously if Mast can't go that's a guy we don't have on the roster but assuming he can I feel pretty ok with where they're at with roster construction
