Antonio Brown is at it again. The free-agent wide receiver took to Twitter on Monday to lob his latest insult at former Pittsburgh Steelers teammate JuJu Smith-Schuster, criticizing him for his play in 2019:

The beef between Brown and Smith-Schuster dates back to Brown's final season with the Pittsburgh Steelers last year when Brown was apparently upset over the fact that Smith-Schuster was named team MVP.

Brown and Smith-Schuster have continued to trade barbs ever since, with most of the venom coming from Brown's direction (big surprise). To Brown's point, Smith-Schuster unquestionably had a down season this year, as he logged just 42 catches for 552 yards and three touchdowns.

However, in defense of Smith-Schuster, the wideout missed four games due to a concussion and a knee injury, and he also dealt with instability at quarterback all season.

Ben Roethlisberger went down with a season-ending elbow injury in Week 2, and from that point moving forward, Mason Rudolph and undrafted rookie Devlin Hodges played musical chairs under center, with Rudolph eventually suffering a shoulder injury that ended his season.

Still, that obviously won't stop Brown from taking shots at Smith-Schuster, who hauled in 111 receptions for 1,426 yards and seven scores while playing alongside of Brown in 2018.

Smith-Schuster, who played his collegiate football at the University of Southern California, was originally selected by Pittsburgh in the second round (62nd pick overall) of the 2017 NFL Draft. He had a terrific rookie campaign, catching 58 passes for 917 yards while reaching the end zone seven times.

Antonio Brown can lambaste Smith-Schuster as much as he wants, but at least Smith-Schuster is currently on an NFL roster.
