Tony Sparano has been on the job for only two days, but he got his first taste of criticism, and it came from the Jets' most famous fan/detractor, Joe Namath. The legendary Jet made his feelings abundantly clear: He didn't like the hiring of Sparano, the former Dolphins head coach, as offensive coordinator. "I'm stumped. I am stumped," Namath said Thursday on his weekly spot on "The Michael Kay Show" on 1050 ESPN New York.
