There are times when we see something occur that's so wacky you literally can't believe your eyes. Your brain can't process the images being transmitted. You deny what you're seeing as possible.
The most prominent moment for me was sitting ringside in Las Vegas when Mike Tyson bit of a chunk of Evander Holyfield's ear.
Watching a New York Jets staffer stick out his knee to trip Miami Dolphins gunner Nolan Carroll on the sideline would rank up there. To find out it was strength and conditioning coach Sal Alosi, a man whose job is to help players stay healthy, only added to everyone's bewilderment.
Had anybody ever seen something like that before?
If you're old enough to remember the 1954 Cotton Bowl, then you would've.
Alosi's takedown brought to mind an infamous play in which Rice running back Dicky Maegle swept right up the Alabama sideline for what looked like a 95-yard touchdown run. Alabama running back Tommy Lewis, without a helmet, jumped onto the field and shoulder blocked Maegle at the Alabama 42-yard line.
Lewis immediately returned to the bench, quickly sat down and covered his face in hopes of not being spotted. But the referee saw what happened and awarded Maegle a touchdown.
Inspired by Alosi's gaffe, ESPN Page 2 writer Patrick Hruby took a look at the most memorable sideline coaching meltdowns, including shots delivered by Woody Hayes and Buddy Ryan, father of Alosi's boss.
