"We know what type of caliber player he is. So it's a challenge. We got to go out there and make sure we're ready to play. I'm pretty sure Peyton is going to get his guys the ball. We've got to do what we do out there."
Thomas caught 94 passes for 1,434 yards and 10 touchdowns last season, while Decker had 85 catches for 1,064 yards and 13 touchdowns.
"Three 1,000-yard receivers, you rarely see something like that," Graham said. "Golly, they got the deep-ball guy, they got the possession receiver guy. That's typically what you want on a team.
"You want different guys that can do everything. Yeah, they've pretty much got it all, so we've just got to go out there and play."
The Ravens are counting on Graham to do a strong job against Welker and the Broncos' other wide receivers.
"They said, 'What about the matchup with Welker?' Well, he matched up with Welker last year," Pees said. "It's not like this is his first parade. He's matched up against him before, and we'll try to do the best job we can and help guys when we can help them."
Graham loves challenges. He overcame a tough background growing up in Buffalo, N.Y., went to a football program that wasn't a big-college powerhouse and was drafted in the fifth round by Chicago in 2007 before being relegated to kick coverage.
"Everybody has been talking about Denver, it is what it is, but we're going to go out there and play ball and do what we do," Graham said. "We're confident in what we can do and we're ready to show everybody else what we can do."
