Coach Ethridge's version of the slot-T used multiple I-formations, A-formations with motion, and a few other sets. The mid-seventies Indians had a strong run game with dives, misdirection, and pitching the ball outside with blockers in front. Another thing that I remember about Coach Ethridge's offenses, unlike the LH and Vidor versions, is that Coach Ethridge's OCs would sling the ball downfield. The TE, swingman, and RBs out of the backfield were passing threats and Richy Ethridge could throw it all over the yard. Richy Ethridge could sling it 10 times a game. VIdor may not throw the football 10 times the entire season. Not sure about LH, but the one video I watched, there was 1 pass?
