The uniform change came during Dungy's second year (1997). Nothing to do with Gruden -- when the Glazer's bought the team in '95 they announced they were getting rid of the creamsicle uniforms.
I stand corrected. Too bad he couldn’t win a Super Bowl with the team he created. It took JG. He won with Payton Manning at Indy. However , I think TD is a great coach too. He banded together scrubs and created great teams.
