Maybe we have a different definition of incredible. I consider that type of a superlative to be reserved for the greats. He isn't in that category at this point.Harbaugh is not an incredible coach. He is a good coach.
And Shaw is average.
Harbaugh took over a 1-11 team and three years later was in a BCS bowl. That's incredible.
Maybe if he had stayed and won a NC. Maybe if he wins a Super Bowl or two someday.
Chip Kelly has won neither a Super Bowl nor a national championship. Do you consider him to be incredible?
