8-4 stand a lone is not a failure or a disaster. but if it is the high water mark of this staff...the peak....it won't be good enough....the only questions one really has to answer is how long do you want to give the guy to get there? and do you think he's capable of it? if you don't think he's capable, then i'm sure that group would say 'the sooner the better'. if you do think he is, then i would expect that group to say 'let's see how we do thru 2018'. i'll say this, and i think he's here thru next year regardless...if we get to the end of next year, and there's still no trip to ATL....i'm not sure what else will need to be said..by anyone.
boro laid out a reasonable expectation level either in this thread or another, can't remember which, and don't feel like looking it up...but basically it said, and i agree with, that we should be competing for the division pretty much every year....i take that to mean we should win some combination of, if not both, the GA and FL games with some semblance of regularity--not go on 5,6 or 11 year losing streaks--and if doing that regularly, we could expect to find ourselves in ATL every 2-4 years or so.
get to ATL and then see what happens after that...win, a lot of doors open....lose, and you still represented your division and gave yourself a shot at bigger prizes.
for a program like TN that fancies itself as one of those blue blood programs, i don't think that's unreasonable.
