Well the D should be much better next year. I am willingto give them the benefit of the doubt this year, there are lots of young guys playing and they are missing their best DB. They have been close to stopping OK ST they just can't make the play but those are plays that a more experienced player might make. If they fail to do so next year then you can talk about a major change up being needed. Problem is the D will likely be better but the offense is likely to suck again with no experience at QB.
