Rob Gronkowski Trolls Teammates Julian Edelman and Tom Brady on Instagram

The New England Patriots' Tom Brady and Julian Edelman have been known to play around on social media with each other, and teammate Rob Gronkowski has noticed.

And he senses that the quarterback and receiver's online relationship has created some favoritism on the gridiron.

This past weekend, Brady hung out with Justin Timberlake at UFC 200. Feeling left out, Edelman used the power of Photoshop to add himself to a picture of his teammate and the entertainer. 

Of course, Gronk saw Edelman's post:

Bruh.

For what it's worth, Gronkowski was Brady's No. 1 receiving target last season. But Edelman is also a favorite, and perhaps the tight end believes some of the wideout's targets should really be directed his way.

Anytime Gronk sees an opportunity to have some fun, you better believe he's going to take it.
