If Bobby Engram excels in Super Bowl XL, that doesn't mean you should move him up on your fantasy football draft board for 2006. If Ben Roethlisberger has an outstanding game, that doesn't mean misfortune won't haunt him in the future.
Past Super Bowl standouts have sometimes been much less of a factor during regular-season play, while outstanding Super Bowl performances have led to just plain bad luck for a few players. Some players use the big stage as just another arena to display how good they are. Overall, when a player performs well in the Super Bowl, that doesn't mean we should overrate him for the next season. Fine Super Bowl outings often don't translate into successful fantasy production the following year.
No player might be a better example of this than Deion Branch, the MVP of Super Bowl XXXIX. In last year's Super Bowl, he caught 11 passes for 133 yards, right after he caught four passes for 116 yards in the AFC Championship Game. So Branch was destined for a great 2005 season, it seemed.
