I'm sorry but the one who's wrong is you. It's a question of confidence and a guy who fumbles once every 84 snaps is not a forward who misses goals. I wish you actually take that into account before labelling anything as awful.
Stop. You're making yourself look silly.
Ridley was scratched for a game after fumbling in three successive games. This bears literally freak all relevance to soccer, and just because it's your main reference point doesn't make it any more correct. You can argue all you like about how it's not productive to drop a young player for repeatedly making the same mistake and there's no definitive right or wrong answer there, but the comparison to soccer doesn't work and no amount of you trying to torture it into place is going to make it so.
So what? They should have lost, he fucked up the timeout thing, does winning the SB mean that he was right? You can make a mistake and win anyway.
Of course it means he was right. His primary aim isn't to make Stevan Ridley a Pro Bowler, it's to win the Super Bowl. You don't win Super Bowls when your lead back is turning the ball over once a game.
