I'm a little less optimistic than some others in this thread, mostly because people seem to assume that NWB and Young will be completely healthy and remain so the whole year. But look at Hans Brase this year. He appeared to have recovered from his injury, only to see it relapse.
Also, everyone seems to be forgetting that our new recruits will *also* be inexperienced freshmen just like this year's and every other year's crop of freshmen.
I think we will improve, though "improvement" will be more like 7-11 or 8-10.
I really only anticipate one freshman seeing significant minutes next year, and that freshman is a borderline 5 star recruit depending on the service you look at. History tells us that the upper tier recruits are usually major impact guys their freshman year.
Plus, the team will be deep enough with returning upperclassmen and transfers that we won't need to rely on freshmen nearly to the extent we have this year. The guys coming back have all played together now for at least one year and will have a better idea of how to work with each other.
Not saying your prediction of 7-11/8-10 is going to be wrong, but I think it's totally understandable to expect better than that.
