Seahawks DL Shelby Harris: 'Stupid' Guardian Caps will lead to 'more head-to-head' collisions

At the end of July, the NFL made Guardian Caps mandatory through the second week of the preseason for offensive and defensive linemen, linebackers, and tight ends. 

Since the league's announcement, the oversized, puffy helmet shells have received mixed reviews from players and coaches. 

On Wednesday, seven-year NFL veteran Shelby Harris, now with the Seattle Seahawks, didn't hold back regarding his thoughts on Guardian Caps. 

While Harris called them "stupid," his reasoning came with a familiar sentiment. 

The league adopted Guardian Caps to curb head injuries and maybe shore up technique. However, Harris believes they might have the opposite effect. 

"I honestly think that you will end up having more head-to-head blows because you're used to having the helmet pad on," Harris said. "I get what they're trying to do now, but I think later on it's going to cause more of a problem."

Several head coaches have raised the same concerns as Shelby, including New York Jets Robert Saleh and Green Bay Packers Matt LaFleur.

Saleh said the softer blow would lead to players using their heads more often. Meanwhile, LaFleur backed their use but worried players wouldn't get properly acclimated to contact to the head.
