As in have the kicker kicking sooner than he anticipated.

"With just 15 seconds left in the AFC championship game against the Patriots in January, the Ravens' Billy Cundiff faced a 32-yarder to send the game into overtime. Like all NFL kickers, Cundiff uses the scoreboard to keep track of downs and where he should be in his prekick routine. As the Ravens stalled at the Pats' 14-yard line, the Gillette Stadium scoreboard showed third down. Problem was, it was wrong, the Ravens say. Unprepared and probably a bit confused, Cundiff was rushed onto the field by screaming coaches. He hadn't missed a fourth-quarter kick all season. But he got a mediocre snap; the laces weren't quite out. His kick came low off of his foot and hooked left. With his teammates looking on in horror and disbelief, Cundiff had just choked -- badly."
