another example was dan riley one of the first HIT advocates he coached at west point during jone's west point trials. he then moved up to Penn state as a strength coach. from there he went on to be the strength coach for the Washington redskins. result the redskins were in the super bowl in 82, 83, and 87 winning 2 out of the three. joe gibbs left the program after that and riley fell by the wayside as a result.
