EAST RUTHERFORD, N.J. – Giants cornerback Janoris Jenkins had a few rough days at training camp. Odell Beckham Jr. can do that to a cornerback who is often matched against one of the league’s best wide receivers at practice.

Beckham beat Jenkins for touchdowns each of the past two days. He also made him look silly on Saturday.

On Wednesday, Jenkins bounced back. The offseason acquisition had three pass breakups (although none was intended for Beckham), including one he should’ve intercepted for a touchdown. Overall, he had a much better day.

Beckham still managed to score his daily touchdown, only this time it came against rookie cornerback Eli Apple.

As for Jenkins, his coverage was praiseworthy. On the first play of team drills, Jenkins reached his hand around and knocked down a pass intended for wide receiver Geremy Davis. He later had Davis blanketed near the sideline to cause another incompletion. Jenkins’ third standout play occurred when he cut in front of wide receiver Dwayne Harris in the slot and had the ball bounce off his hands.

The missed interception aside, Jenkins might’ve had the most productive day for any cornerback this summer. It was undoubtedly his best day.

It’s not that Jenkins’ camp has been poor. In fact, it almost has been what should be expected.

The book on Jenkins with the Rams was that he was physical and made plays but also allowed some deep passes. That’s exactly what has been on display this summer. He has been burned deep by Beckham, Tavarres King and Myles White.

But more often than not his coverage has been solid. He has done everything the Giants have asked. He’s “absolutely” looked good according to coach Ben McAdoo, who has seemingly been asked daily about Jenkins. Sometimes twice in the same day (whoops, my bad).

“He's a great competitor, a good team guy. He's a leader out there and the game is important to him,” McAdoo said.

The Giants need all of that. Jenkins is a big part of their future after they handed him a five-year, $62.5 million deal this offseason.

The infirmary

Wide receiver Victor Cruz (groin), linebacker Keenan Robinson (hamstring) and defensive end Kerry Wynn (groin) sat out practice. Linebacker J.T. Thomas (hamstring) and defensive tackle Jay Bromley (ankle) remained on PUP.

Defensive end Jason Pierre-Paul (stinger), safeties Nat Berhe (groin) and Landon Collins (ankle) and fullback Nikita Whitlock (illness) all practiced.

McAdoo is not messing around

It was a hot, humid and sometimes rainy practice at the Quest Diagnostics Training Center. So when center Weston Richburg snapped the ball over quarterback Eli Manning’s head one play, the Giants could’ve reloaded as is and gone on to the next play.

But that’s not how things work at Giants practice these days. There are no excuses for foolish penalties, mental mistakes, etc. Richburg jogged right off the field and was replaced for a snap by Adam Gettis. Richburg knew the deal, just like offensive tackle Bobby Hart knew the deal when he committed a false start (for the second time in camp) on Tuesday.

If you make a foolish mistake at Giants practice under McAdoo, you’re off the field for a snap. That’s the deal.

Observations

Rookie tight end Jerrell Adams might have a hard time earning a spot on the roster. He has been working with the third team and committed an illegal block penalty during special teams drills on Wednesday. ... Wide receiver Myles White had minor pushing matches with cornerbacks Matt Smalley and Donte Deayon. Maybe White was just in a bad mood. ... Apple also dropped a potential interception late in practice. Granted, the ball was wet as it was moments after a torrential downpour. ... H-Back/tight end Will Johnson caught a touchdown pass in red-zone drills. He had a solid day. ... Logan Thomas had another bad practice. His accuracy was abysmal and he consistently holds onto the ball too long.
