It kinda loses its effect when you make the same prediction year after year after year. Logging on to a Cowboy message board and predicting good things for the team is hardly the definition of "courage." Anybody can do that, and there's no risk of being pummeled.
Consistently predicting disappointment, from a good team, in a league where 31 of 32 go home unhappy each year, on a board that features possibly the largest collection of entitled whiners ever assembled on the internet, now that takes some stones.
