Falcons tight end Tony Gonzalez is strongly considering retirement after this 2010 season. "It is year to year," Gonzalez said. "I could play another three or four years. I know I could ... There's a lot of different factors. Yeah, I'd probably come back but you never know. I'm going to wait." Gonzalez said there is roughly a "50-50" chance he will step away once his 14th season ends. "If you ask me now, I'd tell you I don't know if I'm going to play this year because I'm in (training) camp," he said. "Football is a grind. That's why (NFL) careers only last three years. It's tough on your body. It's tough on you mentally. I'm just fortunate to be playing this long."
