​The New York Giants lost five games due to fourth-quarter collapses last season. Some will point to a lack of depth. Some will blame injuries and a weak roster. Others, however, are more blunt. The Giants just weren’t in great physical condition. They didn’t ramp things up enough in training camp or preseason to the degree where they would be ready for the start of the regular season.In each of the past three seasons, under head coach Brian Daboll, the Giants began the season 2-8 through their first 10 games. Those seasons were over two weeks before Thanksgiving, creating John Mara’s biggest fear as owner: Meaningless football in December and January.That isn’t in the plans this year, with John Harbaugh now as head coach. The Giants are practicing hard, keeping to the task at hand during both the offseason and training camp. On Thursday, they participated in a joint practice with the Miami Dolphins down in South Florida in preparation for their preseason game against them Saturday afternoon. “I felt like we got so much out of it,” Harbaugh told reporters after the spirited scrimmage that contained several fights and altercations. “I’m really proud of our guys. I thought we played some good football out there. And now we’ll be ready to look to play even better in the game.”The practice was held in extreme heat, but that didn’t affect the Giants very much. Chalk it up to Camp Harbaugh, which has held a high standard so far when it comes to conditioning. “I think our guys are in great shape and they had no problem with it. Our guys – we were strong at the end of practice,” the coach said. “We were getting stronger through the practice. I saw that, really, from every single player on the field.”Even though there were fights, Harbaugh didn’t lose his cool, either. He simply polices these things as if it happened in a regular game. When offensive lineman Jermaine Eluemunor threw a punch, Harbaugh benched him. “We decided that anybody that threw a punch in those scrimmages would be treated like the game,” he said of the agreement he made with Dolphins head coach Jeff Hafley. “That’s why Jermaine didn’t practice toward the end. He didn’t really throw a hard punch, but it was to the facemask, and that’ll get you in the game. So, that’s a 15-yarder at least. So, we decided that we were following those rules of engagement, and that’s what we did with that one.”Accountability. Discipline. Focus. Team first.Get used to it, Giant fans. Those principles are here to stay.This article originally appeared on Giants Wire: Giants focus on conditioning to avoid past fourth-quarter failures
