The blocker did not hit the kicker in the head or neck...he hit the dude on the side below his arm pit, check the arm flying upward, the real problem was the way the kicker landed on the hard artificial surface.
The Texas Bowl was by far the absolute worst Texas football game I have ever witnessed....from my perspective it appeared that (1) most of the team did not care about the game & would've rathered being somewhere else, (2) because of #1 there was no fire, emotion or any kind of other passion...
