I agree on PART of that statement.
This is Pelini's first year here as HEAD coach.
We should stick with our base defense most of the time... I mean, the 4-3 is our BASE defense, right?
Why not drill that defense week after week after week until these kids can do it in their sleep?
Once they start perfecting it, stop making mistakes, then possibly think about running your nickel packages or your 3-Man fronts.
New year, new system, new coaches...
But it IS still on the players to perfect what they do... That IS what they are here for, and they SHOULD have faith in their coaches no matter what the coaches have them do.
