Recall that Kansas was just coming off an overtime game with TTech and game where they held Texas to 14 points for 58 minutes and Texas needed final driver to beat them. This was no gimme game - all KU needed was a little confidence on senior night to make this a dogfight. They just about go it in that first quarter with some typical turnovers and the defense needing to find its legs.
Even if the numbers are comparable, there is a huge difference in the area of leadership in aspects like poise, composure, and decision-making. Richardson is just a natural quarterback. He is the QB that looked like the 5th year senior against KU whereas Jantz has looked like a redshirt freshman several times THIS year. If people can't see the tangible difference in the jittery, nervous style of play compared to a cool, confident one I don't know where to go with this topic.
Cheers
