New England Patriots head coach Bill Belichick. BILL INGRAM /THE PALM BEACH POST / USA TODAY NETWORK

The New England Patriots took a major gamble with their coaching staff this offseason, and their experimentation is continuing during the preseason.

The Pats lost offensive coordinator Josh McDaniels to the Las Vegas Raiders. But they didn’t replace him with a proper offensive coordinator. Instead, they have Matt Patricia and Joe Judge looking to split the role even though neither has offensive coordinator experience.

On the first drive of the Patriots' preseason game on Thursday against the New York Giants, Patricia called the plays.

Later when Bailey Zappe came in to play quarterback, Joe Judge called the plays.

Formally, Patricia is listed as New England’s senior football advisor and offensive line coach. Judge is listed as an offensive assistant and quarterbacks coach.

Head coach Bill Belichick was asked after the game about the situation. He said he thought it would be a good opportunity to test it out.

Belichick also indicated that his team is going through a process even with their playcalling. Maybe Belichick wants to see who gets the better results.
