PHILADELPHIA (CBS) — It’s been nearly ten years since the Eagles settled into their nest at Lincoln Financial Field, and the front office is looking at ways in which it can enhance the fan experience — and generate more revenue.

Team president Don Smolenski (top photo) says one of the advantages of traveling around the NFL is getting access a few hours before game time to check out the facilities on the road.

“We are in the beginning phase of our process, just gathering ideas and looking at concepts,” he said today.

Sports Business Journal cites industry sources familiar with the Eagles as saying the total cost of the stadium renovation could be more than $60 million, including adding seats and new field-level suites to generate more revenue.

But Smolenski says the team has not finalized the elements of a construction project.

Mayor Nutter notes that although the Eagles are tenants at the Linc, the Eagles, not the city, would pay for remodeling the city-owned stadium.

“If the Eagles want to make facility improvements to Lincoln Financial Field, that’s a business decision that they make.  We don’t have any financial responsibility for that whatsoever,” the mayor said today.

Right now, overall seating capacity at the South Philadelphia stadium is just over 69,000.
