Hhaha... actually that's not what happened, if you actually watched the game.
The giants had called a TO on the play before, so they couldn't take another timeout. Eli tried to call another time out, but the referee correctly ignored him and they took the delay of game. The delay of game was more incidental than anything else.
Oh, and why didn't a 15 yard unsportsmanlike conduct get called (like it did on Joe Gibbs)?
From Jerry Markbreit:
"Under NFL rules, the same team cannot call consecutive timeouts. If the officials incorrectly acknowledge the consecutive timeout, the clock is immediately started and the timeout negated. There is no penalty for this act, unless the purpose of the second timeout is to startle and cause a false start by the offensive team. In this situation, an unsportsmanlike conduct foul could be called on the defensive team. Under college rules, consecutive team timeouts are legal, and a team could call all of the team timeouts in succession."
Eli was def. motioning for a TO, but he didn't know the rule.
Maturation, yea right!
