With the Bucks in the playoff chase, Jennings wondered why Boylan made an example of him as Milwaukee endured its fourth straight loss.
"I don't see any All-Stars in this locker room," Jennings said.
Jennings was held scoreless for the first time in 281 career games, missing all three of his shots while playing just 17 minutes against the 76ers. It marked the second rough game in less than a week for Jennings, who scored four points on 1-of-15 shooting in a loss to the Indiana Pacers on Friday.
"I think that everyone should be held accountable," Jennings said. "There's no maxed-out players in this locker room. So don't try to put me on a pedestal and just give everyone else the freedom to do whatever they want."
Jennings said he feels he is being singled out by Boylan.
"Of course," Jennings told the Milwaukee-Journal Sentinel. "This is the third time this has happened. We had a sluggish start but we still had a chance to win it. It was there for us to take."
Milwaukee battled back from an 18-point deficit to take an 83-76 lead early in the fourth quarter against Philadelphia before falling apart the rest of the way.
Boylan defended his decision to remove Jennings, who was replaced at point guard by Monta Ellis.
"I just felt like I needed to do something to energize our team," Boylan said. "When you play that position in this league, there comes with it a lot of responsibility. The talent at that position is outstanding. So you have to bring it every single night. If that's not happening, you need to do something."
With their latest disappointing loss, the Bucks (34-36) fell 2.5 games behind the Boston Celtics for seventh place in the Eastern Conference. Milwaukee does still have a comfortable 6.5-game lead over the 76ers for the conference's final playoff spot.
