Jabari Greer claimed the decision wasn't difficult at all, that it merely was time to move on.
"I want to thank the fans for the support that they gave me," Greer told me. "I worked hard to become the player that I'm becoming, and I think they recognized that. The fans, they embraced me and supported me so much.
"Buffalo will always have a special place in my heart. I couldn't have had a better foundation for my career than what I had in Buffalo."
Greer said he's already looking forward to the Saints' trip to Ralph Wilson Stadium this year.
The Bills signed Greer as an undrafted rookie out of Tennessee. He developed into a starter at right cornerback by 2007 and had the best year of his career as he was headed for free agency.
Greer last year recorded 33 tackles, two interceptions (both for touchdowns), nine passes defensed and a forced fumble.
The Bills tried to re-sign him, but when Greer's tour of prospective employers dragged on, they decided on Tuesday to sign Drayton Florence for two years and $6.6 million. The Bills also have sophomores Leodis McKelvin and Reggie Corner.
"It's the next step in my life," Greer said. "But I don't feel any regret or any remorse because I gave 110 percent of me. I appreciated it, and at the end of the day this is the game of football, and things change.
"I'm appreciative of everything that's happened in Buffalo. As you grow, sometimes you have to part ways. That's what we did."
