The Kansas City Chiefs signed free-agent wide receiver Freddie Mitchell Saturday, a month after the Eagles released the troublesome player. Mitchell was at Chiefs mini-camp in street clothes but will begin practicing Sunday, coach Dick Vermeil said. "We're very happy to have him here and I think he's happy to be here," Vermeil said. "He's in a good frame of mind and his attitude is very good." Mitchell, who played in 63 games in four seasons at Philadelphia, fell into disfavor with Eagles coaches and teammates after making a series of controversial and inflammatory statements. He insulted the Patriots secondary before the Super Bowl, and also called out New England coach Bill Belichick. He also criticized his teammates for not backing him and blasted quarterback Donovan McNabb for not throwing to him more. "The plays are going to be there for me to make," Mitchell said after the Chiefs went through a two-hour workout in front of about 15,000 fans. "I just want to help the team win and hopefully be utilized catching the ball. So it's going to be good. I'm happy to be here."
