The Gronk Spike.
How has such a simple touchdown celebration reached astronomical levels of popularity? It's just one guy -- one really beefy guy, mind you -- throwing a football into the ground like it just talked bad about his mother.
"Spike as hard as you can, I guess."
Just how much force of pressure does a Gronk Spike produce? An average of 645 pounds per touchdown, which is somewhere between a kicker booting a field goal (450) and an NBA player's takeoff for a slam dunk (700). You won't believe this, but there's a Gronk Spike calculator for this, thanks to the Herald enlisting the services of Dan Thaler, an organizing member of the MIT Sloan Sports Analytics Conference.
