I'm going to attempt an analogy... at the race track there is always a guy who has a 800 horsepower car, he cannot keep it hooked up and always runs crappy times. His response, more power.... You guys are that guy. You have 4 star qb's but think a 5 is what you need, you have 4 star wr, but think that will help, you have 4 star stud rbs, and are picking a rb. Until you guys can stop the sister Mary's school for the blind on a halfback dive on 3rd and 2 consistently or have your qb take a snap without a slight fear if getting killed that 5 star Qb is worthless.
Answer: DT or left tackle. Those are what would improve Nebraska the most.
