Titans coach Mike Vrabel tweets NFL's own rulebook at league's officiating account to dispute replay in Chiefs-Broncos game

Apparently, Tennessee Titans head coach Mike Vrabel was spending his free Sunday night watching the Kansas City Chiefs and Denver Broncos face off in the evening matchup.
Vrabel's Titans were on a bye. And during "Sunday Night Football," he watched as a review of a Travis Kelce incomplete pass - the Broncos thought it was a catch and fumble that would have resulted in a turnover - was upheld.
The NFL Officiating account explained that "the third element of a catch - time - was not met. Therefore, the ruling on the field stood as incomplete."
But Vrabel responded with an image from the NFL rulebook with the definition of a catch. No other words. Just that image.
I guess he thought it was a catch? Former referee Terry McAulay explained further and said that Vrabel appeared to agree.
