It has to be Homer Rice. His contribution to football is far and away the best. He helped to INVENT the veer option. He was one of the first to run the inside and outside veer. His overall high school record was 101-7 with nine ties. He also was one of the first coaches to pull the playside guard and tackle on toss plays. He was one of the most innovative offensive coaches ever. He created these innovations while being a high school coach. From a national perspective you could say he is the most innovative high school coach, ever... He went on to coach as an assistant at UK, Oklahoma, and later became head coach of the Cincinnati Bengals. He also wrote a couple of the most influential books ever pertaining to offensive schemes (veer). Many coaches still have these books as a part of their library. Pretty good for getting your start in high school. His reputation for x's and o's was unparalleled. I am not a Highlands fan at all, but I do think that Rice has to be number 1 on this particular list. The rest can be mixed and matched but none have made contributions like Rice.
