Standing out: One player who stood out to me during Friday's practice was veteran receiver Marvin Jones Jr. He was making catches all over the field in front of both Darius Slay and DeShawn Shead, who started at the two outside cornerback spots. One thing Jones wants to improve this year are his YAC (yards after catch) totals. He's off to a nice start. – Tim Twentyman

Teo time: Undrafted rookie receiver Teo Redding of Bowling Green made an impression in the offseason workouts, and he didn't slow down on the first day of camp with a leaping catch in the back of the end zone. He might have landed an inch or more beyond the line, but he still made an impression with the catch. – Mike O'Hara

Versatile Diggs: Last year we saw how versatile Quandre Diggs can be in Detroit's secondary with the ability to play both slot cornerback and safety. Diggs played both spots in the open OTA and minicamp practices this spring. During Friday's practice, he lined up in the nickel and then went to safety in back-to-back plays. – Tim Twentyman

Hyder's return: Defensive end Kerry Hyder Jr. didn't want to talk much about the season-ending Achilles injury he sustained in the first preseason game last year, but he looked fast and quick on the first day of camp. If he's close to full strength, he can help the pass rush. He had eight sacks in 2016 in his first full season as a pro. – Mike O'Hara

Getting in the work: Ziggy Ansah might not be able to participate in practice because he's starting camp on the PUP list, but that doesn't mean the talented sixth-year defensive end isn't getting his work in. Ansah was off to the side of practice Friday working pretty darn hard. That included beating a tire with a sledge hammer, going through an entire upper body workout with the big ropes, and then dragging a weighted sled around. Ansah got a good workout in Friday. – Tim Twentyman
