before you get on your moral high horse about understanding what words mean, the majority of people would use the phrases not good and bad interchangeably. If you don't believe me let's look at what the dictionary says.
Definition of the word Bad:
Merriam-Webster: 1st definition - Not good
Dictionary.com: 1st definition - Not good in any manner or degree
Cambridge English Dictionary: 1st definition - Not good, disappointing or unpleasant
Collins English Dictionary: 1st definition - Not good in any manner or degree
I could go on but it appears you have the confusion problem with word meanings, but bottom line, Not Good = Bad.
You have every right to your opinion that the offense was terrible, and as far as points go they scored 60% less than the avg for year and that's not good, or I mean bad, or what ever it is. and they had 405 yards which was about 22% lower than season avg. That's not terrible, but it's not good.
So why not address the 3 scoring drives for CC that took up more than 30% actual game time and 41 total plays? Your opinion is that is nothing but an issue and not horrible. I think this leans more towards horrible. That's what cool because people are free to have their own opinions and are free to express them regardless of what a word means!
