The Bucks are missing Middleton but also DiVincenzo and Lopez, both starters last season also. They still have Giannis and Holiday so they are still formidable but definitely depleted. They can start Portis in place of Lopez so that is fine but still does impact depth but without Middleton and DiVincenzo, their wing rotation and depth is really depleted.
Even without Brown, I feel we should be favored to win this. Play them tough from the start and use our depth to wear them down. Finish them off with a strong defensive 4th quarter when they are spent. Also, take advantage when ever Giannis is resting.
