Pittsburgh Steelers WR Martavis Bryant let his Instagram fingers go wild Sunday night -- dissing' his teammate JuJu Smith-Schuster while complaining about the team.
FYI, the Steelers WON on Sunday -- beating the Bengals 29-14 ... but Bryant only caught 1 pass for 3 yards and is clearly pissed he's not getting the ball more. He reportedly requested a trade last week.
When someone on Instagram told him his WR teammate "[JuJu Smith-Schuster is] better" -- Bryant fired back, "Juju is no where near better than me fool all they need to do is give me what I want and y’all can have juju and who ever else.
