Manning didn't bring his green ball to training camp though, he brought a different colored ball. You can see his new ball in the picture at the top of the page.
Do you know what color that is?
Manning knows what color that is, he just wants to know if you know.
The Broncos quarterback spent part of his press conference on Thursday trying to get a reporter to identify the color of his new football. (Quotes via For The Win)
Manning: Last thing, I know you wanted to know [about] the ball security thing. Did [Head Coach John Fox] give the answer?
Reporter: Same as the green he said.
Manning: It's a different color because of training camp, does that make any sense?
Reporter: So will it be green for the regular season?
Manning: It won't be blue during the regular season, but it's training camp. What color are they during training camp?
Reporter: Blue ball.
Manning: There it is.
Yes. There it is.
