An example of Reaction Time (RT) is when the center snaps the ball to the quarterback and the minute amount of time it takes before the center and the rest of the offense moves into play (whether that be tackling or sprinting off to receive the thrown ball). The offense has to listen carefully for the center to command "hike" and are not allowed to move before he snaps the ball. Though they can't move prior to the snap, once the ball is snapped, they strive to have a quick reaction time as the ball goes into play. A quick reaction time is important to the guards so that the intended receivers have time to get open and receive the ball. Similar with the receivers, a fast RT will help ensure them to outrun the defense and be open for a pass. Sometimes lag can be beneficial for a tight end or wide receiver in order to fake out the defense, but usually a quick RT is more beneficial. Guards should always practice and perform a quick RT to keep the defense in check.
An example of Hick's Law is shown in college football when a receiver on offense tries to break free for a catch, but has to deal with the defense as well. There is an uncertainty about how well or where the defense is going to cover, and this affects how fast the receiver can react. Another example could also be the uncertainty of when a punt or kick returner catches the ball and has to quickly decide which was he is going down the field as an intimidating defense is bearing quickly down on him. After he catches the ball, there is a delay (though a very short one) before he starts to sprint as he looks up and makes his strategy to gain as many yards as possible. In addition, sometimes before he even starts running the defense is already right in front of him ready to tackle.
An example of Psychological Refractory Period (PRP) in the game is when a running back has to dodge in and around players. As he is strategically making his way towards the endzone, a experienced and athletic player fakes the defense out by spinning around or cutting another direction quickly. The defensive player than has to react when he notices that the running back has quickly changed directions. The defensive player is exhibiting the PRP as there is a delay in the time he is able to react to the runners change in direction.
Inaccurate anticipation occurred when Duke quarterback Sean Renfree threw an interception to Alabama. He inaccurately predicted what was going to happen (spatial anticipation) and over threw the ball right into the hands of an Alabama player. This could also be considered temporal anticipation because he inaccurately predicted when the Duke player was going to be in that area. However, correct temporal anticipation occurred throughout the game when Alabama running back (and Heisman trophy winner!) Mark Ingram accurately anticipated when the defense would attempt to tackle him and was able to dodge their tackles.
