 Davis was also the head coach for PSU in the '70s and '80s, where his run-and-shoot offense gained national attention.The silver lining on the dark cloud was that Davis wasn't the only one to benefit and there was another member of the coaching staff who prospered from this particular move.With two vacancies on the coaching staff, it made it possible for Offensive Line Coach Dennis McKnight to be promoted from an unpaid Graduate Assistant, to a salary-earning full-time assistant coach.
