Peyton Manning Denver Broncos jerseys are already flying off the shelves. Here's a breakdown of where to buy the coolest Manning gear.

Peyton Manning may have only been signed by the Denver Broncos last week, but he is already dominating jersey sales, as his #18 duds have been flying off the shelves ever since he held one up at a press conference with the Broncos in Colorado.

Manning, who replaced Tim Tebow as the Broncos' quarterback, has already left Tebow a distant memory in the minds of Denver fans, who are excited to see Manning calling plays in orange and blue.

And Tim Tebow has nothing to worry about, as he was signed by the Jets last week, and is already sweeping through the Big Apple football scene, as #15 Tebow jerseys have hit shelves faster than any item since #17 jerseys for Knicks sensation (and Tebow's friend) Jeremy Lin did earlier this year.
