More or less. He averages 4.0 YPC in his career. He has rushed for over 1,000 yards once, but Motor would definitely outproduce him if he got the same number of touches. He has two seasons where he averaged 3.7 and 3.8 YPC and this year he is averaging 4.0.
His one year above that he averaged 4.3...Motor has always had an average YPC in every year above his best year.
If by consistent, you mean consistently below average then yes.
