It's not that hard to go to Khalil Herbert's 'splits' on espen or whatever sports website you prefer to find that you're entirely full of shit...
He averaged 7 ypc on 1st down (69 carries), 4.1 ypc on 2nd down (51 carries), 5.0 ypc on 3rd down (8 carries), and 0 ypc on 1 4th down rush.
8 carries for 40 yards on 3rd down last year. Yet your dumb ass tries to make it seem like he can only get garbage yards on 3rd and long when the defense can afford to give up a decent chunk.
I get its a pretty big, nay--extraordinary feat to be somehow dumber than Visionless and BR combined, and its almost respectable how you will not be deterred in your undertaking of said endeavor. But you're a complete and utter reh-tard on this matter, and you should sit the fuck down because you don't know what you're talking about.
