There's absolutely no benefit to running onto a football field during a game because situations like that always end with the person who ran onto the field getting rocked by a player or security guard.
You'd think that getting rocked by a player is much, much worse than being on the receiving end of a hit from a security guard, but as we've seen in the past that's not always the case. Plus, apparently stadium security guards actually practice tackling people that run onto the field:
As the old saying goes, practice makes perfect, right?
The only way to be prepared for a situation in which a fan runs onto the field is by practicing that situation, so if (when) a fan decides to take the field this season in Cleveland, security will be more than prepared to make the tackle.
Speaking of making tackles, everyone on the Browns defence balled out Thursday night as they pitched a shutout against the Eagles.
