"It's funny, I remember that first minicamp really well," Armstrong said. "Zach and I spent a little bit of time together. Those were very physical minicamps, particularly Jimmy's first year. It was really like being at training camp without pads on. Zach made almost every play. He just jumped out at you. You turned the tape on to watch practice and he made almost every play. Sideline to sideline. Great linebacker instincts. You could see it right away.

"It's hard to tell sometimes. You have guys flash like that in the minicamps, especially when there aren't pads on, but really what I thought is, OK, that's going to be a big-time special teams player for us and then maybe he's like a fifth or sixth linebacker.
