I think Wall is, surprisingly, underrated.
With due respect to others, including Isaiah, Wall is an ELITE TWO-WAY Player.
He can do what he does (like drop 40 points w/16 assists), while playing exceptional defense.
Unfortunately, the way WAS is built, they NEED Wall AND Beal to have tremendous games to win, because honestly their bench isn't that great/deep. Celtics have been exploiting it well at times.
