Brett Favre is saying publicly that he hasn't made up his mind about whether he'll play in 2010. But he reportedly told another player privately that he's finished playing. Peter King of SI.com reports that after the season, Favre told a fellow NFL player whom he knows well that he's definitely done. "I'm 100 percent positive I'll never put on pads again in my life," Favre told the unnamed player, according to King. However, as King astutely points out, that doesn't mean much because Favre changes his mind all the time. He probably sincerely meant it when he said he was 100 percent positive he would retire. And a few days later he was probably 100 percent positive he would return.
