Matchup problems. Thon's length made it harder for the blazers to penetrate. They also gave Deandre Liggins, a 6'6 SG they just signed a couple days ago the start, due to matchup problems and the added pressure he could put on 3J.
Blazers aren't used all the length that the bucks have. Thon was effective at disrupting most of Nurkic's shots mainly off of his physical stature, during the first half. Only reason we didnt see more of thon is because got he into foul trouble.
TLDR: Maker and Giannas will be a serious problem in the league 2-3 years from now.....Bucks are building a dynasty.
