FOXBOROUGH, Mass. — What happens when an unstoppable force is also an immovable object?

In New England you call him Trent Brown.

The Patriots’ 6-foot-8, 380-pound offensive tackle has stonewalled defenders of all shapes, sizes and speeds this training camp. He’s swallowed up pass rushers and flattened run defenders. Brown doesn’t protect or block on a given down so much as he unapologetically dominates.

Were it not for cornerback Stephon Gilmore, there’s an argument to be made he’s been the best player on the New England practice fields this summer.

Lining up across from Brown, Patriot defenders have still yet to figure out a reliable recipe for beating the behemoth. Whether in one-on-ones or team drills, the task of defeating Brown is as tall as he is.

“He’s just a guy who you can’t really go around,” defensive end Trey Flowers said. “Definitely can’t go through him. You’ve got to find a way to get him to move his feet or whatever.”

Between the two choices, “whatever” is actually more likely to garner success. For as large as Brown looms, he’s also stunningly athletic. On two occasions in 11-on-11 sessions, the former San Francisco 49er has led the charge on screens. The defender nearest Brown on each snap was instantly eclipsed.

“He’s light on his feet,” Coach Bill Belichick said. “He has good balance and is a good athlete for a man of his size.”

Speaking Saturday after practice, Flowers echoed Belichick’s thoughts.

“I went up against him in San (Francisco) so he had some decent feet then. But he’s definitely a guy that you can look at and think he’s not as athletic or he doesn’t move as well, but you’d be surprised. He’s definitely a great addition to the team.”

Ultimately, fighting all of Brown’s tools requires using the sharpest of your own. According to eight-year veteran Adrian Clayborn, who clashed with most offensive tackles in the league during his time with the Bucs and Falcons, competing with Brown demands your best.

“Your decisions have got to be faster. You’ve got to be preciser and you’ve got to use all your strength,” he said.

In the second practice of camp, second-year defensive end Deatrich Wise Jr. managed the seemingly impossible: two defeats of Brown in the same practice period. Wise, whose rare length is his own gift, relied on his length and mental acuity to beat the left tackle.

“My moves are just reactions off what the guy in front of me gives me,” Wise said.

Still, Wise, especially going against Brown, has been quiet since then during one-on-ones. He, like Clayborn and Flowers, has attempted to spin, swim, bull and speed rush against Brown. Occasionally the two draw but most often it’s a clear defensive defeat.

The odds of beating Brown again are equal to finding another lineman just like him.
