“I can’t speak for (Jerod) Mayo and Spikes, but from my standpoint, I’ve just got to do what I was coached,” Hightower said. “I made one mistake and tried to correct it on different techniques and things that didn’t work that I should have known wouldn’t work. But after talking to (linebackers) coach (Pepper) Johnson and looking up to Mayo and Spikes, them talking to me on the sideline and all through this week, they’ve been in my corner. “I definitely feel like this week was a big improvement for me. Whenever I have those two guys and Pepper Johnson in my corner, I can only go up. Those guys have really helped me a lot this week.”
