It's what I see as realistic. 8 wins is two more than his first two years, and now it's his recruits and as I said, three years with Haze's boys. I'm really surprised you don't expect 8 wins this year. And I don't think I'm being abrasive at all.
With a red shirt sophomore expected to be pressed into duty on the offensive line, among other uncertainty, I don't see how you can expect anything other than improvement.
It takes a lot of time to shore up the line of scrimmage in recruiting and development, and only takes a few injuries to jack that up.
There is very little separating 5 wins from 8 wins, depending upon how the football gods behave.
