Swift has been most impressed with Bieniemy's attention to detail.
"The detail on everything jumps out to me," Swift said. "It's the little things—little things that are big things. It's the detail that comes with every single day, his energy and his football knowledge; he's very intelligent."
Harris played in 194 games over 14 seasons with the Eagles (1998-2002), Packers (2003-2009), Dolphins (2010) and Rams (2011). A two-time Pro Bowl selection, he registered 21 interceptions—three of which he returned for touchdowns—140 pass breakups and 470 tackles.
As Bears defensive backs coach/defensive passing game coordinator, Harris regularly taps into what he learned as a player.
"That's exactly what I fall on, because \[there's\] no better person to do that than if you've been in those situations," Harris said. "If I'm a truck driver, I want a truck driver to teach me. Not that someone who wasn't a truck driver couldn't teach me because they study it, but I rely on those experiences to inform the guys and mentor the guys."
When cornerback Tyrique Stevenson was preparing to visit the Cowboys prior to the 2023 draft, he researched Harris, who was Dallas' defensive backs coach at the time, seeking out his game highlights.
Now that they're together with the Bears, Stevenson is eager to learn from Harris.
"I think it's going to help me a lot because it's coming from a coach who played my position, did it at a high level and did a great job at it," Stevenson said. "He'll be able to provide little tips, like if your feet are pointed in a certain way.
"His résumé speaks for itself. He said today, 'I would never teach y'all anything that I didn't truly believe in myself and I didn't do in a game. I'm teaching you something that worked for me, and if you can add this to your game, it will help your game.'"
