Ben McAdoo wasn’t even an hour into his summer vacation but already had managed to squeeze in a session on the treadmill.

Back in his corner office and still sweating, he pulled out his disposable contact lenses and tossed them in the trash. Taking a seat, he slid on his glasses and fielded a question: Next season — his first as the head coach of the New York Giants — will be a success if ... ?

“We put the fifth (Super Bowl) trophy in the case,” he said, without hesitation. “Period. That’s it. There’s only one goal in this business.”

It was the last day of New York’s offseason program. Most players had split — freedom for six weeks. Same for coaches.

Kind of.

McAdoo had mapped out the next day. He’d see a play, featuring his daughter, Larkin. Then, he and his wife, Toni, would attend parent-teacher conferences.

Once they got home, he’d work until dinner time, watching film of New York’s defense and special teams from offseason practices, glancing ahead at opponents, and, above all else, sharpening his situational football — what he said he needs to focus most on.

“Every day in this office, there are about three dumpster fires you have to put out,” McAdoo told USA TODAY Sports, deadpan, in a sit-down interview last month. “I feel if I’m willing to work before office hours and after office hours, then I’ll be able to handle those dumpster fires well, in the right frame of mind, and have composure doing so.”
