edge - and Doman's superior execution of the option made that happen. If you rewatch 2001 video the thing that jumps out (and one time I actually measured this) is how many long runs Luke had where he was essentially untouched. If I'm not mistaken he had over 600 yards rushing that year on about 20 carries in which he either scored a TD or went out of bounds basically with no contact.

And most of that was the product of Doman nailing a pitch that got Luke the edge.
