Odell Beckham Jr. isn't in the NFC East anymore, but he still is finding ways to troll Dallas Cowboys stars Dak Prescott and Ezekiel Elliott.

Ezekiel Elliott posted a picture on Instagram with him and Prescott celebrating with the caption “21 x 4.” The caption refers to the two offensive stars' jersey numbers, but Beckham helped them solve the math problem right in front of him.

In the comments section, Beckham commented “84,” solving the math problem 21 multiplied by four. It's clear that Beckham was just having some fun, but “21 x 4” could be a scary duo this season for the NFL.

Even without Zeke getting a normal workload in game one, but he still ran for 53 yards and a touchdown. He only had 13 carries and is looking for a bigger workload this week.

“I didn’t get a lot of reps — didn’t get close to the normal work load,” Elliott said Wednesday via ProFootballTalk. “I had a couple of bruises, but I felt pretty fresh.

“I think I’m ready now for a normal workload. It just depends on how GB [running backs coach Gary Brown] and Kellen [Moore] and coach [Jason] Garrett are feeling on Sunday, but if they ask, I’ll be able to go out there and do it.”

The good news for Beckham and the Browns is they aren't in the NFC East, so they won't have to play each other this season unless they meet in the Super Bowl. For now, the only interaction between these two teams will take place in the comments section of Instagram.
