There may have been no audio of Kenseth's rant, camera too far away, etc. But you do know the gist of it, and you have the Drama Queen's interview upon leaving the infield care center. "The 22 ran me off the track... I thought we were done with that, but maybe we aren't." I'm surprised he didn't say Logano lifted his rear tires off the ground, as that is his favorite claim when touched.
Logano did force Kenseth below the yellow line. Only Drama Queen 20 would claim it was deliberate and personal. And then Logano checked up to let him back in line.
