have to agree w/ glaity - use a more neutral base formation and only use ND box or Trips when you have to.
you are losing the turnover battle. 11 touchdowns to 15 interceptions is not good, especially considering you have a good roster. you either have a predictable offense or your settings are too aggressive, or both.
here's a one-off tip. i like to pair opposite offensive formations in early down situations. i.e. - pro set, heavy pass, aggressive & pro set, heavy run, conservative. one of those formations is likely to win out if the defense sells out against a certain type of play.
