Defensive coordinator Aaron Glenn, offensive coordinator Ben Johnson and special teams coordinator Dave Fipp spoke to the media Friday ahead of Detroit's Monday night matchup in San Francisco against the 49ers. Here are my 10 biggest takeaways from those media sessions:

1. Detroit's defense got defensive back Ifeatu Melifonwu back in the lineup last week vs. Chicago and he ended up playing 80 percent of the snaps at safety allowing Brian Branch to play the nickel and Amik Robertson to push outside with Carlton Davis III (jaw) out. Glenn loves the versatility Melifonwu gives him and said there's some packages with him playing dime and nickel they didn't get to in Chicago he plans to utilize with Melifonwu more moving forward.

2. Fresh off the heels of that successful 'stumble bum' trick play in Chicago last week, Johnson opened his Friday presser shouting out assistant coaches J.T. Barrett, Steve Oliver and Seth Ryan who are responsible for coming up with a lot of those special plays. Johnson said there is some pretty off-the-wall stuff that comes across his desk and credits those three with a lot of it.

3. Who stood out watching the film of the 49ers' special teams? Fipp said rookie punt returner Jacob Cowing is one of those players. Cowing is currently top 10 in the NFL in punt return average (8.5 ypr). Fipp said he also respects the fact that wide receiver Deebo Samuel goes back and returns kickoffs and said he's darn good at it.

4. Who is the best tight end in the NFL right now? Easy answer for Glenn, who said it was the 49ers' George Kittle just because of everything Kittle brings to the position in both the pass and run games.

5. The first game Penei Sewell ever played in his NFL career was against the 49ers back in 2021. Johnson was asked to reflect on Sewell's first season and how far he's come since. Johnson said it was the game against the Rams in 2021 when Sewell battled Aaron Donald one-on-one, held his own and then got into it with Donald sticking up for himself and teammates as a point when Johnson first knew they had something special in Sewell.

6. Fipp explained the false start penalty on long snapper Hogan Hatten that made Jake Bates' end-of-half field goal attempt last week 65 yards and not 60 yards. Fipp said the linemen got into their stance too early while Bates wasn't set up yet, and when Hatten really dug in to snap the ball back and lowered his hips, the ball moved. Fipp said it was the right call by the officials and a teaching moment for his group.

7. Robertson did a nice job moving from the nickel to outside cornerback spot in Chicago. He allowed just two receptions in the Lions' win and was tough in the run game. Glenn wasn't surprised by the performance at all. He said it was actually a bigger adjustment for Robertson to move inside in his scheme when he was playing more outside cornerback in Las Vegas before signing with Detroit. Glenn loves Robertson's experience, pit-bull mentality, swagger and confidence.

8. Rookie Christian Mahogany started his first game in place of the injured Graham Glasgow last week and Johnson thought it was a terrific outing by Mahogany. He showed a terrific first step and some of the nastiness in his game the Lions noticed in him coming out of Boston College.

9. It's nice to see wide receiver and primary returner Kalif Raymond back at practice. Fipp echoed that sentiment but he also commended the job Maurice Alexander and Tom Kennedy did fielding punts and making that a smooth operation without Raymond the last month.

10. The re-signing of veteran quarterback Teddy Bridgewater helps all phases of the team, Glenn said, even his defense. Glenn said Bridgewater is one of the biggest trash talkers he's ever been around and has a way of (ticking off) a defense and motivating them. Glenn said he and his defense are looking forward to going against Bridgewater in practice moving forward.
