Mr. Everything: Veteran safety Quandre Diggs was the only defensive back in the NFL last year to finish with at least 75 tackles, three interceptions, three tackles for loss and one pick-six. He’s played both safety spots and both inside and outside cornerback during his career. He was a quarterback in high school. During Thursday’s first practice of training camp, he was also among a group of players that included Jamal Agnew, Danny Amendola, Brandon Powell and Tom Kennedy returning punts. Is there anything Diggs can’t do on the football field? – Tim Twentyman
Tavai fitting in: Jahlani Tavai looked at home with the starting linebackers in the offseason workouts, and he was just as comfortable at the start of training camp. The second-round draft pick from Hawaii worked with the No. 1 unit. The way he communicated with teammates between plays showed that he was not out of place. – Mike O’Hara
Playmaking rookie: Rookie first-round pick T.J. Hockenson made a few nice plays in his training camp debut. The team’s No. 1 pick this past April snuck behind the linebackers and caught a touchdown in the back of the end zone in the last rep of a goal line passing drill that forced the defense to do pushups. Later, in 7-on-7’s, he made a leaping catch in the corner of the end zone and was able to get both feet in bounds for a touchdown. – Tim Twentyman
Center of attention: Frank Ragnow was at center from the first snap. We can end any speculation of whether the move to center from left guard – where he started all 16 games last season as a rookie – was an offseason experiment. – Mike O’Hara
First five: Speaking of the offensive line, there are a lot of question marks about the starting left guard spot this camp. As expected, the five linemen with the first-team unit Thursday were Taylor Decker, Kenny Wiggins, Frank Ragnow, Graham Glasgow and Rick Wagner. We’ll see if things change Friday. – Tim Twentyman

Rookie debut: Fourth-round draft pick Austin Bryant of Clemson did not participate in offseason drills while recovering from an injury, but he looked comfortable doing drills Thursday – including dropping back in coverage. – Mike O’Hara
Sitting trio: The first practice of training camp took place without defensive end Trey Flowers (PUP), cornerback Darius Slay (NFI) and defensive tackle Damon Harrison Sr. (NFI) on the field. All three were standing together chatting off to the side at the beginning of practice. It was a lot of defensive firepower in one trio. Those guys are arguably Detroit’s top three defenders. It will be hard to evaluate Detroit’s defense until all three get between the lines. – Tim Twentyman
