When Mike Leach added David Yost to the coaching staff many wondered how big of an impact Yost would have. He came in as the inside receivers coach, but has a long history as an offensive coordinator.
WSU Athletics produced a "mic'd up" video with Yost and watching it, it's obvious he's doing more than just coaching the inside receivers. During the practice, he works with essentially everyone on offense, including the quarterbacks. Oh, and his hair is still glorious as ever.
While he isn't on Mike Leach's level, Yost is a quote machine throughout the video. Among the highlights was Yost telling a receiver to not run to get tackled and telling someone named Wilson -- presumably linebacker coach Ken Wilson -- "I coach until they stop me Wilson."
