While taking the program to heights not seen in decades is not mediocre. He came into a mediocre program. He reached rarely achieved heights at the school over a multi-year period. He left in a similar state, as he entered.
There are loads of Hall of Fame coaches with that path both recent and throughout college football history. It doesn't change anything about their careers or how they setup the program to continue after them. Jesus. Tech fans are ööööing miserable when they take great joy in ööööting on their own program's accomplishments. Why don't you tell me what Johnson's FBS record was during even years, since we're just cherry picking the last 4 years or whatever?
Collins' spiel about what GT should be works largely because of the accomplishments during Paul Johnson's tenure.
Conference championships?
CFP bowls?
Beating Top 10 teams at night in BDS?
Remember all that öööö he promised? You think that's easier sell to recruits and gets the fans more fired up over cause they can actually remember it that last time? Make that sell at GT vs some school without that recent pedigree. Cause prior to that we either had to go back to 1990 or for öööö's sake - the 50s and 60s. That would sound even more dumb if he was promising that. O'Leary couldn't even deliver that.
And ya, I do admire Paul Johnson. I can accept with great joy his accomplishments and realize he trailed off in effectiveness. He still left the school in a better place for it.
