Keys to the game for more me would be:
Pressure Garrett Gilbert, he's proven to be a below average QB with guys in his face and Texas this year seems to be a little soft up front on the line, but if you give him time to step up and make a big throw he can hurt you, don't give this kid time in the pocket b/c that's when he will be lethal.
Pound it at Texas, with Rex and Roy in the backfield Taylor doesn't have to bust a big run or try to do it himself every play, people say Nebraska hasn't been hit the mouth yet, well that's b/c our lineman have a done a great job all year long with their physical play, if they play physical and contain Sam Acho and the rest of that D-Line and create holes for our backs they both could have a big day.
My next point is keep those big plays coming, this is a team that quit against UCLA in the final quarter and never really got to the same level as Oklahoma the score was closer than the game I thought, this is a young team that will get down on themselves if they give Nebraska a couple big plays. Set the tone against them and they will struggle.
Finally limit turnovers and create a couple, Prince is due for an int. and against Texas receivers who are a little down this year still trying to find that new Jordan Shipley, Malcolm Williams isn't doing as much as they thought he would so this is the perfect game to lockdown on receivers, and going back to earlier putting pressure on Gilbert forcing him into some bad throws and mistakes will be key, and for Nebraska keep the ball off the turf, and Taylor Martinez don't try to force anything that isn't there and make sure he reads his coverages and isn't throwing into heavy traffic or trying to make throws he can't make.
