Matt Patricia makes Lions debut Monday night against Jets

DETROIT (AP) — Matt Patricia has appeared to push the Detroit Lions more than they ever were under Jim Caldwell.

The Lions seemed to run more and hit more. And, they may have gotten yelled at more.

On the practice field over the last several weeks, it wasn't hard to see or hear Patricia.

The burly man with a bushy beard and a pencil over his right ear moves around a lot, spending time with various position groups during drills to share his expertise on both sides of the ball. He shouts to get his point across at times, including once when he didn't like the pace in which players were moving from one field to another.

How does Patricia avoid overloading his players?

"Probably in the end you really don't know until after the game, unfortunately," Patricia said recently. "But you try to do a good job of gauging your players and how they're handling the week. And obviously there's a constant communication with the players to say, 'Are we good on this? Do you think we need more? Do we need to cut back? Do we need to scale back from that standpoint?'

"I would say it's always the biggest challenge early in the season because you're kind of just really getting into that mode for the first time."

And for the first time, Patricia will be an NFL head coach in a game that counts Monday night in Detroit against the New York Jets .

The 43-year-old Patricia declined to share his emotions entering a big day in his life, keeping people guessing, much like his mentor has done for years. He was on Bill Belichick's staff for 14 seasons, serving as his defensive coordinator the last six years.

Many years earlier, Patricia began his path to leading a team in the league by matching wits with buddies while playing electric football. Patricia, who is from Sherrill, New York, would set up miniature players on a vibrating, metal field to face off with friends in games that would continue for weeks.

"I knew at a very young age the strategic part of the game was something that I just loved," Patricia said when he was hired in February.

When the Lions hired general manager Bob Quinn two-plus years ago, the former Patriots executive chose to keep Caldwell in 2016 and gave him a contract extension the next year. Quinn had his eye on Patricia over the last two years and cleared a path for them to reunite by firing Caldwell after last season's 9-7 mark wasn't good enough to put the team in the playoffs.

Even if Detroit got into the postseason and lost, Caldwell might've been replaced by Patricia.

Soon after New England lost in the Super Bowl, the Lions landed the coach they wanted by hiring Patricia, who earlier had other suitors.

Detroit's players liked playing for Caldwell. His cool and calm ways were respected and they appreciated that he cared about them off the field. They found out quickly Patricia was bringing a change of pace: a demonstrative and louder leader.

"The way he came in just set the tone right away," Lions linebacker Jarrad Davis said. "He came in, he laid down the law. He gave us the rules and he came in with energy."

No one in the NFL is really sure what a Patricia-led team will look like because what he showed in the preseason is not expected to be anything like what he'll do in Week 1 against the Jets. Especially with New York starting a rookie quarterback, Sam Darnold.

Jets coach Todd Bowles, though, knows what Patricia's defenses looked like with the Patriots.

"They're always very smart," Bowles said. "They're always very tough-minded, and the execution and fundamentals are outstanding. He's brought that to New England, I'm sure he's brought that to Detroit. They've always been tough. He's handled us quite a few times, so we have our work cut out for us."
