We’d expect no other kind of response from Rob Gronkowski.

Already this week, Broncos linebacker Brandon Marshall said that Gronk pushes off to get open and defensive end Antonio Smith essentially called Patriots quarterback Tom Brady a crybaby.

Where those smart comments to make leading up to the AFC Championship game? You can be the judge of that.

What’s arguably caused a greater outcry is what Broncos cornerback Chris Harris Jr. said on ESPN about tackling Gronk.

“You gotta hit him low, man—hit him in his knees,” Harris said on SportsCenter, via Mile High Report. “You gotta take his legs out or hold on and wait for everybody, wait for the gang to come on and gang tackle him.”

That’s not a dirty comment—it is wise to hit Gronk low, and the NFL frowns on high hits, anyway. But somehow, Harris’s comments were blown out of proportion, prompting Gronk to playfully respond on Twitter.

Heard their whole team is good at giving low blows 😜🏈 https://t.co/nDOsOwkvki — Rob Gronkowski (@RobGronkowski) January 19, 2016

Gronk’s tweet obviously had a double meaning. It was a “distasteful” remark, according to KUSA-TV’s Mike Klis.

It's getting real I see lol — Brandon Marshall (@BMarshh54) January 20, 2016

There’s already been a lot of talking between these two teams, and it’s only Tuesday.

Sunday’s going to be fun.
