That depends on whether you see the glass as half full or half empty.
For example, in 6 years, Fedora has 0 (zero) OOC wins over P5 teams that finished with a winning record. And he is O-fer the SEC, including losing to a SoCar team that finished 3-9: which, coincidentally, is the UNC record for 2017.
Spurrier resigned halfway through that season, so bad was the team and so ineffective the coaching.
And then there is Brandon Harris. Some will see Fedora getting him on scholarship here and then giving him the starting job as a sign of utter incompetence in QB evaluation, and others will see it as a potentially brilliant move because just maybe Harris could have lived up to his original recruiting evaluations if he played for Fedora.
Now, some will see those facts as negative about Fedora, and some will see them as positive. We may call those camps Annoyingly Negative and Pollyanna Positive. Both are here. If both are not there, then there is missing half the discussion. Some would say the Pollyanna Positives require segregation from things they cannot answer or face. Some would say they are keeping the peace by demanding no annoying negativity. Half full, half empty.
It doesn't require 6 or 7 years to rebuild a program into stability. Scott Frost took a winless team and got it to a bowl his first year, and to an undefeated league champ his 2nd. Lane (son of not Monty, but Monte with an 'e') Kiffen took a team that won 9 games over 3 years before he arrived and won 10 games his 1st year.
