We've been bringing you detailed practice reports from Giants training camp each day. But some observations just don't make the cut for those reports. So, here are some under-the-radar observations from the first week of camp:

Dropping the ball

Brandon Marshall has been everything the Giants expected since they signed the six-time Pro Bowler this offseason. Marshall is the big receiver the team lacked last season, and he's made impressive catches over cornerbacks Janoris Jenkins and Eli Apple in training camp.

But if there's one red flag with Marshall that has flown under the radar it's a tendency for drops. Even when Marshall was producing monster stats, he was consistently near the top of the league in drops. That has continued in training camp, with Marshall dropping an easy pass periodically. It's not a huge concern, but don't be surprised to see it crop up during the season.

QB school

Giants coach Ben McAdoo told Davis Webb that he'd be put into "QB school" after he was picked in the third-round of the draft. The Giants have started with the basics with Webb. That includes practicing taking snaps under center, which is new to Webb, who spent his college career operating out of the shotgun in Air Raid offenses. The Giants have the luxury of time with Webb and they are showing no signs of rushing his development.

Not bracing it

Geno Smith looks 100 percent after tearing his ACL last October. Need evidence? Smith isn't even wearing a brace on his surgically repaired right knee. There have been no limitations on Smith during training camp as he battles Josh Johnson for the backup quarterback job.

Domino effect

Aldrick Rosas learned how fragile job security is in the NFL last week. Rosas had been the only kicker on the Giants' roster since the start of the offseason, but the Giants signed veteran Mike Nugent on Tuesday after the abrupt retirement of undrafted free agent safety Jadar Johnson. Rosas always knew it was possible that the Giants could add a kicker. But if Johnson didn't retire, it's unlikely Rosas would have a competitor in camp right now. The pressure hasn't affected Rosas, however. He hasn't missed a kick in a team period during camp.

Extra long

Store this away in case long snapper Zak DeOssie gets injured during a game this season. Linebacker Mark Herzlich, defensive tackle Jordan Williams, fullback Jacob Huesman and tight end Colin Thompson have taken reps at long snapper at the end of practices. All of those players will be on the roster bubble, so long-snapping is one more way to earn a spot.

DRC in and out

Dominique Rodgers-Cromartie returns as the slot cornerback, but he has also been getting work outside. Rodgers-Cromartie is the top backup to Janoris Jenkins and Eli Apple outside, so he needs to stay sharp. Apple rarely comes off the field, so Rodgers-Cromartie has mostly taken Jenkins' spot when lining up outside.

Herzlich catching on

NFL coaches value versatility, so Herzlich continues to add to his repertoire. In addition to his work at linebacker, special teams and backup long snapper, Herzlich is also getting reps at tight end. Herzlich only plays tight end in a 7-on-7 period for inexperienced players at the end of practices. The 6-foot-4, 246-pounder has looked smooth running routes and has good hands.

Touchdown! Davis Webb finds Travis Rudolph for a deeeep score-GM pic.twitter.com/qdn2CTMhOs — The Giant Insider Newspaper & Podcast (@GiantInsider) August 2, 2017

The Giants have a 7-on-7 "opportunity period" at the end of each practice. Here are some of the notable players that participate in the period: Quarterback Davis Webb, running back Wayne Gallman, tight end Evan Engram, tight end Jerell Adams, wide receiver Travis Rudolph, cornerback Mykkele Thompson and safety Eric Pinkins. The young players receive instruction from McAdoo and both coordinators during the period.

End arounds

One wrinkle to the Giants' playbook in training camp is more end-arounds to wide receivers. Odell Beckham Jr. has taken the handoffs most frequently. It's always a good idea to get the ball in Beckham's hands as often as possible. Speedy receiver Tavarres King has also been involved in the end-arounds.

Fun with competition

McAdoo puts a fun twist on offense vs. defense competition periods at the end of practice. On Tuesday, players held two balls and then tried to catch a third ball as a punt returner. Beckham and Rudolph were successful for the offense, while only cornerback Donte Deayon made the catch for the defense, so the whole defense did push-ups. On Wednesday, linemen tried to throw a ball into targets on a net. Guard John Jerry was the only player to hit the target, resulting in another win for the offense and more push-ups for the defense.

Dance party

Don't Edit

The Giants don't just reserve their dancing for the locker room. Warm-ups are part stretching, part dance sessions for a number of players. Beckham and Rodgers-Cromartie are the players who spend the most time dancing on the field.

High markers

Dan Duggan | NJ Advance Media for NJ.com

Even when the Giants run 7-on-7 drills, quarterbacks don't get a clean look at their throwing lanes. Staffers hold up yard markers along the line of scrimmage in place of defensive linemen. Josh Johnson is the only quarterback to have a pass broken up by a marker in camp.
