Double tight ends: T.J. Hockenson (first round) and Isaac Nauta (seventh) were taken in opposite ends of the draft, but they were almost in sync with TD catches a couple minutes apart. First, Hockenson made a tumbling catch in the left corner of the end zone. In the adjoining field, Nauta made a catch in stride on a post pattern on his way to the end zone. – Mike O'Hara
Rotating guards: One of the better position battles entering camp was expected to be at guard, as the Lions look for a replacement for T.J. Lang. Kenny Wiggins worked with Graham Glasgow at the two guard spots with the first-team offense on Thursday. Friday, Joe Dahl and Oday Aboushi played the two guard spots with the first team. It appears that competition is very much up for grabs, and the Lions are going to get a good look at everyone. – Tim Twentyman
Self-punishment: Cornerback Andre Chachere made a nice breakup with a diving effort just in front of the right corner of the end zone, but he apparently wasn't quite satisfied with the result. He dropped down and did 10 quick pushups. – Mike O'Hara
Hill work: The Lions have installed a hill north of the east field at their Allen Park training facility. The Lions use it for rehabilitation, conditioning, improving lower-body strength, lengthening run strides and protecting different muscle groups, among other things. Friday, it was put to use by defensive end Trey Flowers, who continues to rehab an injury, during practice. – Tim Twentyman
Drill of the day: Head coach Matt Patricia stresses ball security. In one drill to improve that, players caught the ball, maintain control when an assistant coach jabbed at the ball with what looked like an oversized padded stick, then evade contact from a defender closing in to swipe at the ball. – Mike O'Hara
Low on linebackers: Outside linebacker Devon Kennard sat out Friday's training camp practice. Midway through the session fellow veteran linebacker Christian Jones left the field with a trainer. It left the Lions a little low on veteran linebackers. – Tim Twentyman
Rookie vs. rookie: In a goal line 7-on-7 drill, Hockenson and second-round pick Jahlani Tavai found themselves matched up in the end zone with Hockenson running a corner route. Hockenson was able to leap up and make the grab over Tavai, who had pretty good coverage on the play. Detroit's first two picks in this year's draft are already getting after it in camp. – Tim Twentyman
