WHITE SULPHUR SPRINGS, W.Va. — The New York Giants are into the grind of training camp, with Monday’s practice starting a stretch of six straight days of practice. The team wore full pads for the first time Monday, and coach John Harbaugh indicated that will be the case on Tuesday and Wednesday, as well.“The second week is the big week of camp. This is your opportunity to really grow as a football team,” Harbaugh said. “You build your foundation in training camp for your team. The second week should be where you cover the most miles, gain the most ground. We want to put the most miles behind us as far as developing the foundation of our team. This is just a go-to-work week.”There’s plenty of work to be done after a sloppy, penalty-filled practice conducted in torrential rain. Here’s everything you need to know from Monday’s practice:John Harbaugh is making his mark early at Giants training campDan DugganAttendanceCornerback Jarrick Bernard-Converse and defensive tackle Roy Robertson-Harris weren’t spotted at practice. Robertson-Harris remains on the physically unable to perform list with a torn Achilles tendon. There was no word on Bernard-Converse’s absence.Injury reportWide receiver Malik Nabers, who was only wearing a helmet and shells, went through position drills and took reps in a jog-through install period. That’s been the consistent workload for Nabers as he rehabs from a torn ACL and torn meniscus.Rookie cornerback Colton Hood was checked by trainers after a physical shoulder-to-shoulder collision with running back Dante Miller. Trainers appeared to be checking Hood’s shoulder, but he returned to finish practice.Second-team center Lucas Patrick, who missed part of the spring, didn’t participate in team periods. He was replaced by Bryan Hudson.ObservationsImpact player?Outside linebacker Abdul Carter burst onto The Greenbrier practice fields and announced his excitement for the first padded practice of camp. That enthusiasm was evident in another strong performance by the defense.The most physical practice of camp allowed inside linebacker Arvell Reese to show his potential impact. Reese was closing in to blow up running back Tyrone Tracy Jr. on a swing pass early in practice that fell incomplete. Reese was in the backfield twice to stop Cam Skattebo behind the line of scrimmage. Those plays showed how quickly Reese was processing and reacting. His physical skills made him the No. 5 pick in the draft, so it’s encouraging to see him playing fast so early in camp.The most intriguing play of practice came in the first-team offense’s two-minute drive at the end of practice. Trailing by five points with 56 seconds remaining, the offense started on the defense’s 48-yard line. On third-and-5, Reese beat left tackle Andrew Thomas around the edge for a sack. Reese hadn’t moved around much early in camp, but his versatility is what gives him the potential to be a game-changer.Rain, but no shineIt was a slog for Dart while dealing with driving rain for the middle stretch of practice. His first pass was a smooth completion to wide receiver Calvin Austin III on a curl route on third-and-5. Dart’s best throw was a deep ball to rookie Malachi Fields during a 7-on-7 period. Fields has made strides toward establishing himself as a deep threat. The concerning aspect of the play is that Fields beat cornerback Paulson Adebo, who has surrendered a high volume of completions during camp.Dart threw an ugly interception during a 7-on-7 period, but the rain was a valid excuse since the ball clearly slipped out of his hand and fluttered into the arms of safety Jevon Holland. Dart double-clutched and then tried to throw deep, which wasn’t advisable in the wet conditions.After focusing mostly on first and second downs in the first week of camp, there was an emphasis on short yardage on third and fourth downs on Monday. Dart lowered his shoulder on a fourth-and-5 designed run, which served as a reminder that he’s not going to change the way he plays.
