Swearinger took issue with the team playing man-to-man on a third-down play that resulted in a holding penalty on cornerback Fabian Moreau. He was also angered about the decision to put Moreau in that position against Titans backup quarterback Blaine Gabbert.
"I felt like we should have been more aggressive," the 27-year-old Swearinger said after the 25-16 loss. "I feel like on the third down and six, third down and seven, we're playing a backup quarterback, why would you put us in man-to-man? We are our best on defense when we look at the quarterback. When you go one high on a backup quarterback, that's easy, man. It'll go backside every time.
"I feel like if we look at the quarterback with all this time we've got on the back end, man, we can dominate every team, every week. I'm not the defensive coordinator though, so..."
Swearinger didn't stop there when asked if he went to Manusky with those issues.
"I express my frustrations every single time I come off the field," Swearinger said. "I'm a very smart football player. I probably watch more film than the coaches. ... I'm trying to give my insight but it doesn't work.
"I can only put my heart in this [expletive], dog, put my heart in this [expletive] and give them what I can give them. Whether they take it or not, that's another thing. That's where the frustration comes."
Gabbert entered the game in place of Marcus Mariota, who exited with what the team called a stinger. The journeyman quarterback completed 7-of-11 passes for 101 yards and the game-winning touchdown, a 2-yard pass to tight end MyCole Pruitt.
Swearinger has voiced his frustration several times this season, namely with the team's preparation as well as a casual Friday practice atmosphere.
The 5-foot-10, 205-pound Swearinger has four interceptions, 53 tackles and one sack this season for the Redskins (7-8).
