Wizards are in the 11th (15-30) position right now, and they are coming from a lost to Hawks.
While Bucks are still on top, so even without Giannis I think they can still do better and beat the Hawks because of Middleton, Bledsoe or George Hill and Ilyasova who can carry the team.
This is an exciting game, we are about the find out soon, yes, Bucks did great last time when Giannis was absent but it's not guaranteed it will again happen.
