Who is the better tight end, Ertz or Gronkowski?

Not everybody believes Rob Gronkowski is the best tight end in the NFL.

Guesting on the NFL Network’s Good Morning Football on Friday, Washington safety D.J. Swearinger was asked his opinion.

“I’d have to give it to Zach Ertz,” he said of the Philadelphia Eagles’ leader in post-season receptions. “I like him, and I like (Travis) Kelce right behind him. Then I’d have to say Gronk.”

Gronkowski suffered a concussion in the AFC Championship Game, and while he did not participate in the New England Patriots’ walk-through on Friday, a source told the Boston Herald the team is “optimistic” he will play in Super Bowl LII in Minneapolis on Feb. 4.

But while a two-week recovery would be in accordance with at least four other Patriots who suffered concussions this season, everybody’s situation is different. And until Gronkowski receives medical clearance, his status will be of great concern.

Meanwhile, Swearinger seems to know his stuff.

This season he finished tied for first on Washington with four interceptions — and also scored big time with a prediction moments before a Week 10 meeting with the Minnesota Vikings, when footage shows a young fan asking him to get three interceptions.

“I’m going to get you two,” Swearinger replied.

Washington lost the game 38-30, as Case Keenum threw for more than 300 yards and four TDs. He was also picked off twice. By Swearinger.

“I feel like I’m going to be one of the top safeties in this league,” Swearinger said when GMF pressed him for a prognostication of his 2018 season.

“Shooting to be No. 1, but top three is where I am right now. We can continue to take steps forward.” As for the tight end debate, consider this: Gronkowski was the league leader at the position with 1,084 yards on 69 catches. Next was Kelce (1,038, 83 catches) followed by Ertz (824, 74).

All three had eight touchdowns. Earlier this week, Ertz weighed in with his thoughts.

“The guy’s a physical specimen,” Ertz said of the six-footsix, 265-pound Gronkowski. “He’s a freak. He’s a beast after the catch. He’s able to use his body even when he’s not open to get open with the frame he has.

“He’s definitely been the premier tight end in the league for a long time (and) I think he’d still be producing those numbers without Tom Brady.”

When it comes to Gronk, that’s the heady stuff Patriots fans would prefer to be talking about.
