Accountability, I agree with your sentiments. If a player is being outperformed in practice, he really has no right to see the field. People can debate all they want that athletic ability trumps scheme knowledge, and vice versa, but this is Pelini's MO. I'm sure Pelini tells them this when he is recruiting them - they know what they're getting into. If the fans don't like it, all I have to say is tough luck - it probably isn't changing.
What I think needs to happen, and I'm sure Beck would say "Well, duh", is we need to find ways to get these guys the ballduring their limited playing time more-so than they did. Turner has a lot of speed as witnessed in the spring game, yet we barely saw any of that this year. Turner is well-suited for WR screens and reverses, or as a back in the diamond formation with his speed.
A lot of this comes down to Turner stepping his game up, and Beck growing as an OC.
