Goal line: For the second straight day, practice began with the goal line drill. Head coach Matt Patricia explained in his daily pre-practice press conference that it's a vital part of the game for both the offense and defense. There really isn't enough time to work on it thoroughly once the season starts. Camp is a good time to drill home the basics. – Mike O'Hara
Injury scare: Wide receiver Marvin Jones Jr. suffered a leg injury after going up for a fade in end zone. Jones got tangled up with cornerback DeShawn Shead, who came down on Jones' legs. Jones got up and walked a few steps before going back to the ground where he was tended to by trainers. After a bit, Jones got up and tried to walk it off. He remained outside for the rest of the practice, and looked fine walking back to the locker room after practice was over. – Tim Twentyman
Beckham-esque: It wasn't full speed in the goal line drill, but middle linebacker Jarrad Davis showed some athleticism when he jumped to make a one-handed interception. It didn't match Odell Beckham Jr.'s classic one-hand highlight catch, but it was good enough for the second day of camp. – Mike O'Hara
Impressive passer: Matthew Stafford is among the top quarterbacks in the league, so he should look pretty good in training camp, but he's been very sharp the first two days of camp. He's fitting balls in tight windows, completing back-shoulder plays with receivers and tight ends, and very few of his passes are hitting the ground. – Tim Twentyman
Common connections: Theo Riddick and Golden Tate have been two of Matthew Stafford's favorite targets, and he went to both for touchdowns in a short span in one red zone drill. On the first, Stafford started to roll right, stopped and hit Riddick down the seam after Riddick had read the coverage to get open. A little later Stafford made a sharp throw to Tate, who caught the ball in the right front corner after a play fake to the left. – Mike O'Hara

In the mix: Patricia is very active during practice. He gets around to a lot of different position groups. The offense was going through a 11-on-11 running period, and Patricia was standing right where the linebackers would be, getting an up-close look and instructing throughout. Later, during a defensive walkthrough period, he was right in the middle of the defense talking things over with veteran safety Glover Quin about certain alignments. – Tim Twentyman
Leg work: The Lions have a history of bringing kickers and punters to camp who have no real chance of beating out the incumbent but have gone on to land jobs with other teams. Punter Ryan Santoso, a 6-foot-5, 258-pound rookie from Minnesota with a powerful leg, could be another candidate. – Mike O'Hara
Special returner: Jamal Agnew, Golden Tate, Ameer Abdullah and TJ Jones were the contingent of punt returners during Saturday's special teams drills. Agnew was impressive in that capacity last season, and he showed why again on Saturday. He caught a ball on the right hash and outran the coverage to the left sideline. He's fun to watch with the ball in his hands. – Tim Twentyman
