If you add up the number of Super Bowl titles of the two teams Ryan Mundy has played for, you'd get X.

The New York Giants and Pittsburgh Steelers, who have each won two championships in the past 10 years, share an intimate history, growing from ownership ties and their decades in the NFL. Mundy, after spending the first five seasons of his career as a Steeler, switched families in March, making for a smooth transition during this week's minicamp and beyond.

"Coming from one first-class organization and going to another one is definitely a plus," Mundy said.

"It starts with ownership and management and coaches. To have that stability and that formula for success and the right way of doing things, it's definitely a plus for a player. It allows you to focus on being the best that you can be and know that people are here for your best interest, and they're here to see you succeed."

They're also here to see if he can become the Giants' third safety. In coming to New York, Mundy joined the competition -- which includes Will Hill, Tyler Sash, and drafted rookie Cooper Taylor -- behind probable starters Antrel Rolle and Stevie Brown.

After winning the Super Bowl as a member of Pittsburgh's practice squad as a rookie in 2008, Mundy played all 16 games in each of the last four seasons with five starts, including the first three games of 2012. There Mundy learned from some of the best, playing under famed defensive coordinator Dick LeBeau and behind Pro Bowlers like Troy Polamalu and Ryan Clark.

 "Just how to be a professional," Mundy said about what he took away from his time in Pittsburgh. "I was there for five years. It was a veteran team for my whole time period there, and just being around guys like Troy, Ryan Clark, James Farrior, Aaron Smith, all those guys – they showed a young guy like myself how to be a professional. That helped my transition here because I know how to work, I know how to practice, I know how to focus in meetings."

Aside from joining a likeminded franchise, Mundy also reunited with Brown, who was a freshman at Michigan when he was a senior. Brown, who broke out in 2012 with eight interceptions, slept on Mundy's couch the summer before football season in Ann Arbor.  Apparently, he frequently returned without much notice.

"During that summer, freshmen would come up and stay with upperclassmen who had apartments, and he was staying with me and [current Cincinnati Bengals cornerback] Leon Hall," Mundy recalled. "He would always call me when he was 15 minutes away, wouldn't give me a heads up like a couple days before – 'Hey Ryan, I'm coming up.' He would call me literally 15 minutes before he got off the exit to my house like, 'Are you home?' I'm like, 'Can I get a heads up or something?' But Stevie is a really good guy, a great player."
