My worst ever: My QB had a bye week, so I picked up Rex Grossman for the infamous Cardinals/Bears Monday matchup. He had a 0 rating, 6 turnovers, and i got -11 points. I had actually already locked up the victory on Sunday. Denny Green's blowup will always be stuck in my head because I too was pissed off that night.
Since, I have twice locked up victories on Sunday and benched any players I had going on Monday night.
My best spot start ever? Jamaal Lewis, when he put 4 TDs on the Hawks with only 30 or so yards rushing. I was thin at RB, picked him up hours before the game. He hadn't done much that season, but I knew that the Hawks stunk in early road starts.
a close 2nd goes to when I once gave Tony Romo a spot start early in his career on a Thanksgiving day game, and he threw 5 tds. Pure luck, and desperation on my part to even start him.
