The Bucks need to rebound the ball
Milwaukee has gotten dominated on the offensive glass this series.
Indiana has the size advantage against Milwaukee currently, as Brook Lopez being the only true bg means Indiana can feast on the offensive glass.
Indiana is averaging 11.3 offensive rebounds in this series, and it's because outside of Patrick Beverley, no guard on the Bucks roster has the mentality to clear the glass.
Winning a championship involves luck and the will of everybody to do everything. Not only has Milwaukee relied on Lillard, Middleton, and Giannis to carry the scoring load for most of the season, but they've relied too heavily on Brook Lopez to anchor the defense. At 36 years of age, it becomes more difficult to ask Lopez to continue to be that guy.
Milwaukee takes a step back defensively when Giannis or Lopez aren't on the floor or aren't playing. Those two cover up the defensive defecincies that exsist on the roster.
Not to say Beverley or Crowder aren't good defenders, but they don't impact a game like Giannis or Lopez.
Rebounding aside, this comes down to Indiana being a bad matchup for Milwaukee. Aging rosters don't win championships in the NBA because when you go up against a young, upstart team, their youth can run you off the floor.
Milwaukee has been in trouble this series when Indiana has gone fast tempo on offense because they can't keep up defensively.
Milwaukee needs one more break to go their way. Can the team extend the series to a Game 6, or will they bow out in Game 5 for the second straight season?
Can Bobby Portis, Pat Connaughton, AJ Green, Pat Bev, and Andre Jackson Jr. step up and help on both ends of the court?
Can Milwaukee at the very least rebound the basketball at a consistent clip?
All of those question and more will be answered Tuesday night.
It'll be interesting to see what happens.
