The Chiefs were going to give it the old high school try.

Before their helmets finally arrived in Foxborough on Sunday afternoon in time for their game against the Patriots — after about 35 of their equipment bags had been mistakenly sent to Newark — the Chiefs had devised a backup plan with a local high school so they wouldn’t have to forfeit the game.

With some help from helmet-maker Riddell, the Chiefs were set to use the helmets from the Masconomet Regional High School football team, according to the Tri-Town Transcript. The school’s helmets are nearly identical to the Chiefs’ helmets — except for an “M” in the arrowhead instead of “KC” — and Masconomet was only about 50 miles from Gillette Stadium.

A Riddell representative got a police escort to the school to pick up the helmets and brought them back to Gillette Stadium, only for the Chiefs’ own equipment to finally arrive less than two hours before the 4:25 p.m. kickoff.

“As far as we know he went down to Foxborough with them,” Masconomet athletic director John Daileanes told the newspaper. “They had a contingency plan in place to use our helmets. Who knows whether or not these helmets would even fit properly. There’s a way to kind of make them fit. But I don’t know. It would have been great. I just wanted to see one random Masco helmet. I thought that would have been pretty classic, but it never came to fruition.”

Instead, the Chiefs won 23-16 in their own helmets, saving Daileanes from being in a tough spot.

“I’m a diehard Boston sports fan. I would not have wanted to be responsible for a loss,” Daileanes said. “I probably would have had to change my identity.”
