"It's a tremendous opportunity, most definitely," Allen said. "To roll with the starters, they're a close-knit group, and I'm new to the team. So, to be able to play with those guys and get an opportunity to play a lot of snaps with them, it's going to be a great opportunity to be part of that."
Allen was signed as a free agent in the offseason to replace Tyrone Carter as the backup free safety to Clark. Allen also provides a significant upgrade on special teams.
He was a two-year special teams captain during his six years in Tampa Bay, but also started 24 games between 2005-06 before losing his job to rookie Tenard Jackson in 2007.
"That's the way the game is,'' Allen said. "Initially, it was a letdown, but you have to strap your boots up and make do with what you have, and I think I've done that. Throughout my career, I've fought adversity."
Allen came from Tampa Bay's "Tampa Two" defense and has found learning Dick LeBeau's zone-blitz scheme defense hard to grasp, as many before him have claimed.
LeBeau's defense is more of a read-and-react style compared to a cover style of a Tampa Two.
"Initially, it was a little tough for me to learn, but I'm starting to pick it up better every week," Allen said. "I'm understanding the concepts, but it's a growing process. And as long as you play fast and play physical, everything else will fall into place."
Allen has gotten more and more comfortable, and it shows on the field. He had two tackles against the Giants Saturday and added another on special teams.
"Will Allen is a great player, and he made a lot of good plays for us last game," linebacker Lawrence Timmons said. "I can't wait to see him out there."
The main reason the Steelers signed Allen was his special teams play. Allen said he already feels like one of the leaders on the unit this year, even though he has been in town less than six months.
"I definitely feel like a leader," Allen said. "We've got some young guys, some young rookies and second-year players who need to learn how to play special teams in this league. It's different than it is in college. I played at a high level in Tampa."
Allen said he is up for whatever is asked from him.
"Whether it's in a starting role, as a backup or a special teams ace, whatever it is, I'm willing and ready to do it," he said.
