ALLEN PARK, Mich. -- It took a day, but the Detroit Lions were finally able to practice outside Saturday for the first time during training camp after morning rains made for cooler-than-expected conditions in the Detroit area.

Sunday, though, is when the real excitement will begin, with Lions coach Jim Caldwell said the team will have its first padded practice at 2 p.m. ET. But for the non-padded work, here’s what stood out Saturday.

1. Drops were an issue all day: Rookie tight ends Adam Fuehne and Ben McCord had real troubles hanging on to the ball. Both had bad drops -- multiple by Fuehne and one by McCord that literally hit him in the hands and then fell out. At least one of Fuehne's drops happened during a drill in which he was uncovered. In all, I counted at least six drops by pass-catchers Saturday, including by Fuehne, Jeremy Kerley and rookie Dwayne Washington against air. Ball security has been an issue for Washington dating back to minicamp.

2. A surprising star of the day ... Quinshad Davis: His work came mostly during second-and-third team reps, but the undrafted free-agent receiver from North Carolina had a good day. In individual drills, he had an impressive, one-handed catch in the back of the end zone. Davis also had a nice grab in the end zone during 7-on-7 drills on a pass from Jake Rudock. It was tipped, but Davis kept enough concentration to grab the ball for a touchdown. Davis also caught a pass in the back of the end zone from Dan Orlovsky in the air. He then fell to the ground and completed the process. It was a route similar to the one where he had the one-handed catch against air. The 6-foot-3, 218-pounder has a rough road to a roster spot, but plays like that will get him noticed.

3. Johnson Bademosi's coverage has been rough: It has only been two days, but the cornerback has consistently struggled no matter which receiver he has been facing. He had issues Friday in one-on-one drills with receivers and again in team drills Saturday. Some of that has to do with seeing Marvin Jones in some matchups, but it’s been a consistent theme through two practices. Bademosi is a special-teams ace, but his coverage skills so far have not been impressive.

4. As of now, Jon Bostic should have a role: The linebacker for whom Detroit traded this offseason has taken a bunch of first-team reps next to Tahir Whitehead with DeAndre Levy sidelined on the non-football injury list. The job is still Levy’s whenever he returns -- he’s one of the best linebackers in the league -- but Bostic’s early emergence speaks to where Detroit might view him this season. The Lions have a lot of competition at linebacker and it’s early to make any sort of proclamation, but Bostic is putting himself in position to make the roster.

5. Returns will be wide open: A plethora of players have been taking return reps during special-teams periods. Golden Tate and TJ Jones, the team’s punt returners last season, are both back there. Running back Ameer Abdullah, who was Detroit’s kick returner in 2015, took reps there Saturday. Jace Billingsley, Kerley and Andre Roberts have also been back there getting some work. Jones had a particularly good punt return, but without pads and hitting it’s tough to say how good it really would have been.

6. This and that: The Lions had full participation again Saturday other than the players on physically unable to perform and NFI lists. ... Gabe Ikard received some work with the No. 2 unit at center. He, Travis Swanson and Graham Glasgow are in a competition for the job this fall. ... Corey Robinson was once again working off on the side with assistant strength coach Dominic Raiola, perhaps signaling he’s close to returning.
