Boomer Esiason says mismanagement by the Giants' quarterback and coach in the final two minutes of Sunday's loss to the Cowboys makes him wonder about their overall achievements.

"It's mind-boggling that these guys actually won Super Bowls," the former NFL quarterback says on Tuesday night's "Inside the NFL" on Showtime.

On first- and second-and-goal with less than two minutes remaining and the Giants leading by three points, Manning said he told Rashad Jennings not to score a touchdown if the Cowboys allowed him to do so.

Manning admitted that was a mistake, fueled in part by his confusion over the number of timeouts the Cowboys possessed. Then on third-and-goal from the 1, the Giants threw an incomplete pass that stopped the clock. Coughlin said it was his fault for the call and it should have been a run; Manning said he should have taken a sack rather than throw it away.

"There were so many things that were mishandled by Eli Manning, and by the coaching staff of the New York Giants," Esiason said. "I have nothing but respect for Tom Coughlin, but he's a guy that I think has to take a hold of the decision-making on the sidelines. He deferred to Eli and as we were all watching it on third down, when he threw the ball and it was incomplete and the clock stopped, every single person said the Cowboys have a chance because they mismanaged it."

Jets wide receiver Brandon Marshall, an analyst on the show, said teams go over situational football every week on Fridays and Saturdays.

"They just miscommunicated," Marshall said. "They made a mistake. Fans and media want players to take accountability. He did. He stood up and said it was my fault. How long are we gonna beat this dead horse?"
