Don't know if it's across the board or just Spencer, but he said on a podcast that he doesn't watch tape or game plan for anyone. He just goes out and wrestles, and it usually works.
Tony Ramos and Gilman have also said they were shocked when they left Iowa and saw how comparatively little live wrestling other programs do. Tony said they do drill at Iowa but the majority of practice time, at least when they were with the Hawks, was live goes, conditioning, and strength training. Said Coleman Scott spends a lot more time with drilling and instruction and less time live wrestling. Gilman said similar, that there's a lot of "just rolling around" in the PSU room. The brutal practices worked for Gable, but I think wrestling has changed a lot since then and the spaghetti wrestling and scrambling today leads to more injuries IMO.
