I'd say his "legacy" is already solidified based on last year alone. Heck, I look at guys like Andrew Zow (as one example) and in my eyes they have their "legacy" status.
(Semantics, maybe? Personally, there's a difference in "legacy" and names "writ in Crimson flame." But, then again, is if fair to say Van Tiffin didn't have his name "writ in Crimson Flame" despite the lack if NC's)
I look at things like Hurts averaging over eight yards per carry and that with carrying, on average, 12 times per game. I understand people looking at that and interpreting it in a lot of different ways--most common reaction(s) seem to be fear of injury.
I'd be more in that camp if he was getting hit a lot in the backfield (blind side shots, etc.) when he's scrambling. So far we've seen very few, if any, get a good shot on Jalen.
Pardon the comparison but I think you'll get it ... I look at Jalen, so far, a lot like I've seen the careers of Shaun Alexander and Emmitt Smith. I'm not comparing running talent(s) here, but how they avoid those solid hits from defenders. It's the main reason those two had such long careers.
