They're the same size, same age and both went from Tim Tebow (F-150) to Peyton Manning (F18).
They're both country, both heartthrobs and both as quiet as a Las Vegas Sunday morning.
They became the youngest teammates in NFL history to go for more than 1,000 yards and 10 touchdowns in the same season.
They have the same agent, same marketing guy and once lived together as rookies.
"They're the exact same guy," says Denver Broncos teammate Greg Orton, "just different colors."
Until game days, that is.
On most game days in Denver, Eric Decker's mom flies in from Minnesota, sits in the stands and often has dinner afterward with Decker and his fiancée, country music singer Jessie James.
On most game days, Demaryius Thomas' mom puts on her white No. 88 T-shirts, along with 30 of her closest friends, and watches Demaryius play on one of the little TVs at the women's federal prison in Tallahassee, Fla. The T-shirts are white because colors aren't allowed in the prison.
