That'll teach me to stick my neck out for you.
Let's have a look at what other RBs are doing this season then, shall we?
Here's a ranking of all Division I rushers. The only player with more attempts, TDs, and a higher YPC is
LaMichael James, a strong Heisman candidate. That strikes me as pretty phenomenal.
YPC is
the stat. A RB has no direct control over how many carries his coach chooses to give him, or how often his number is called in the red zone. The stat over which he has the most control is YPC, which is why it's the most cited.
Scat backs often rack up tons of yards and gaudy YPC, but they give way to power rushers in the red zone, lowering their TDs. Some backs play with other very good backs, so-- like Gray and Wood this year-- they end up sharing carries, thereby lowering their total yardage numbers. Penalizing a RB for either of those things is stupid.
I respectfully disagree. Your definition of "phenomenal" is absurd. You're correct that Montee Ball (and LaMichael James) have had statistically better seasons than Jonas; it's no surprise that both are dark horse Heisman contenders. They also play in different systems than ND's, and Montee Ball in particular has played against a far weaker schedule.
Jonas' stats are phenomenal. You don't have to be top 3 RB or a Heisman candidate to have a phenomenal season.
