I agree that voting for Gable would be a good idea in terms of giving the wrestling community the best chance of having a wrestling coach head the list because of his notoriety and recentness.
I will say however though, if we want to really vote for the greatest coach, we should be voting for Coach Ed Gallagher who created the dynasty at Oklahoma State. His teams won 11 NCAA titles in 13 attempts. His dual win-loss percentage is the highest as well. His teams had 19 undefeated seasons. How then did they only win 11 titles, you ask? His teams were kicking butt 10 years before there even was an NCAA tournament, so he would have won even more. All of Art Griffith's championships at Oklahoma State can be directly attributed to Gallagher. Gallagher died of palsy complications and pneumonia while still young. He knew he was dying and hand picked Griffith, who was building a dynasty at Tulsa Central, to replace him. He wrote wrestling books and most of the holds used were developed by Gallagher under the influence of his engineering background. He was the first President of USA Wrestling and was known as "the Father of Amateur Wrestling". He also coached an extremely successful track program at Oklahoma State.
I agree that Gable is great. Was and is a great wrestling coach. I take nothing away from him. He has done so much for the sport of wrestling and has helped tremendously to take our sport to another level. He deserves a lot of credit. But, I also must say that the road was paved long before he got there. Gable was great but he stood on the shoulders of giants like Gallagher, Robertson, Keen, Griffith and Roderick. Gallagher created the program at Oklahoma State whereas Gable took over a program at Iowa that Gary Kurdelmeier had already taken to the top. Gable inherited alot. Gallagher inherited nothing. Plus Gallagher was born and raised in....that's right....Kansas.
