9. New York Gian... Value: $1.3 billion
Owners: John Mara, Steven Tisch

The Giants celebrated their second Super Bowl title in five seasons in February, led by MVP Eli Manning (above). MetLife acquired naming rights to the New Meadowlands Stadium last year, filling a glaring hole in the stadium's financial picture from when it opened in 2010. MetLife was paying $7 million annually as a cornerstone partner, but the naming-rights deal is expected to cost more than $400 million over 25 years. It would represent the biggest naming-rights deal for a current NFL stadium (Farmers Insurance has pledged $23 million per year if a new stadium is built in Los Angeles). The stadium, home to both the Giants and Jets, is scheduled to host the 2014 Super Bowl. (Getty Images)

Quarterback Tom Brady (above) is just the second quarterback, after John Elway, to lead his team to the Super Bowl five times.
