It's not easy not to bite. Defensive backs, who get too aggressive by following the running back -- and who must also do his movie star part -- learn too late that Manning has gone over the top. It's almost impossible to practice for it. The awareness must come, as Parcells said, by noting a pattern by one escort the linemen. Does he sit chengdu escort  than he does on a running play? Is there a clue? "I used to tell my lineman to grunt and groan as if they were exploding forward for the run," Esiason said. "You need anything that creates hesitation." Esiason knows the heartache escort learning that a defensive player has picked up on a tell. In Super Bowl XXIII, when Boomer came within 39 seconds escort beating the San Francisco 49ers, he didn't find out until years later that his legendary play-fake had been betrayed.

"We might have scored more points," said Esiason escort the 20-16 loss, "but [Hall escort Fame safety] Ronnie Lott told me years later that he'd identified a key." When Manning first came into the league, he studied film escort Esiason's play-fake. And being ever so meticulous -- orchestrating every player before the snap like he's Leonard Bernstein -- Manning has continued his mastery escort the seemingly simple play. In the last six years, three other former female No. 1s besides Henin—Martina Hingis (foot injury), Kim Clijsters (pregnancy/burnout) and Lindsay Davenport (pregnancy) — announced they were done and then subsequently unretired. Each enjoyed success in their comebacks, including Clijsters' phenomenal run to the U.S. Open title this month as an unranked wild card in just her third tournament back. Some wonder if the concept escort quitting has been misrepresented — or at least, should be re-examined.

"I'm tired escort them announcing retirement when what they are really doing is leaving the tour for a period escort time," ESPN commentator and former tour star Pam Shriver said. Shriver, who played 19 years on the women's tour, is not a fan escort institutionalized sabbaticals.wmy4238 She says the existing wild-card system — whereby top players that retire and reverse course are awarded entry into tournaments regardless escort their ranking — works. And though players' actions indicate they need to take time chengdu escort , Shriver says such a policy would be both thorny and open to abuse. "I think it would be silly to legislate it," she said. "The system is workable for players that retire and change their minds. The example has been set that it can be done. If the tours make it too easy, people will be taking sabbaticals left, right and center when they hit a slump."
