Last year, he had 5/59 against the Texans in the playoffs but that game was an all system failure for the Browns. In his previous playoff game against the 49ers when he was a Cowboy (the infamous Dak run up the middle game) he had 6/64/1..
In 2018, he went 7/106 then 6/65/1 in two playoff games with Dallas.
So yeah I don't really know what you're talking about. Can't be worse than Diggs in the playoffs.
