I do not think that they we will see a comeback from them. Lillard did play in their last game but they still fell short. Maybe they can win some games against the Pacers, but that's it. It could be 4-2 in the end.
Lillard did struggle with his shot (4-13 FG), but he’ll likely bounce back at home. Remember what the Bucks did in the 2021 Finals? They were down 0-2 but won four straight to claim the title. To all Bucks backers here ... keep the faith. As long as Giannis plays at MVP level, this team always has comeback potential. 
Indeed that's a different lineup which composed of 2-way players like Jrue Holiday and PJ Tucker both players gave Giannis aid to Giannis as they really good in defending stars, I used to remember how Tucker defend KD when they meet in the second round, those kinds of defense helps them to reched and earn the title.
Though let see how Dame will respond with that poor performance knowing him there's always a surprise with Giannis putting everything and trying to win it will be a different situation when playing at home.
