At first he was confused, having previously thought the days of two-win seasons were behind him.
Then he was annoyed, having had quarterback Matt Schaub yell at him for stopping on a route. Johnson yelled back and walked off the field in a heat-of-the-moment reaction.
After that game he was asked if he's happy being with the Texans going forward and he said: "I'm under contract," adding that there wasn't anything he could do about that. In the same interview, Johnson said he's always said he wants to be in Houston, but the tone of the interview certainly seemed as if he was having doubts.
Then came the acceptance of a bad season that was soon to be over. That's the Johnson we saw today.
"There wasn't anything fun about it," he said. "I just hope I never have to experience it again."
Again, Johnson, who isn't in a contract year, was asked if he wants to return to Houston.
"I would love to be back," he said. "I always said I wanted to finish my career as a Texan. That is my plan."
I asked Johnson if next season will feel like starting over, and he said he won't know the answer to that until he sees what the Texans do at quarterback -- whether they bring in a rookie or a veteran.
In a sense it will be a new beginning one way or another.
"I love Matt like a brother," Johnson said. "We don't know what the future holds. I spent eight seasons with him. He was very positive on my career, and I was very positive on his. We both meant a lot to each other throughout our careers."
