What could have pushed this summer's stadium schedule over the top was a matchup of international soccer teams. Chelsea and AC Milan drew more than 71,000 fans to M&T in 2009. A year later, Inter Milan-Manchester City drew less than 37,000 in the lead-up to the World Cup.
"We've got good soccer fans in the area," Cass said. "They will come to see premier teams. They won't flock to the stadium to see teams that aren't premier, or when premier players are not going to play much. The World Cup kept good players out last year. If we had a premier match, we would do very well."
The Monster Jam, meanwhile, is a family-oriented event with potential to become a staple of Baltimore's summer. A 16-truck lineup is coming in July.
"One of the reasons we decided to do the stadium was how strong the Monster Jam event was in 1st Mariner," said Ken Hudgens, the chief operating officer for Feld Motor Sports. "The arena show and the stadium are much different. In the arena, you're much closer to the trucks. In the stadium, the trucks have way more room to operate — bigger jumps, more speed. I think the fans will really love it."
Hudgens said he expects a crowd between 35,000 and 50,000.
"It takes a while to build a market for Monster Jam," he said. "It doesn't have the name recognition the Ravens have. In other markets across the country, take Atlanta or Orlando, it's built over time to where now those events at the Georgia Dome or Citrus Bowl are perennial sellouts. That's our hope in Baltimore."
Correction: An earlier version of this story said that the Ravens couldn't bring a soccer match to M&T Bank in 2010. It was this year.
