Norman would have almost certainly coached while he was in the Navy...
The U.S. armed services took athletic competition within their ranks very seriously in the WWII era and afterward. All the major bases had competition in most major sports and most played schedules as impressive as most college teams.
If a 30-35 year-old guy enlists in the Navy in 1940-41, and puts on his entrance application that he had coached a national championship college basketball team, he would almost certainly have been assigned to coach basketball on naval bases like the Great Lakes Naval Training Center in addition to being a Chief Petty Officer or whatever else he was assigned to do.
(They wouldn't particularly care about his NCAA suspension for slugging the player, he wouldn't be coaching college kids in the Navy but sea-hardened recruits. Plus there would be MP standing right there if he took another shot at anyone.)
So it's highly unlikely if Norman Dale got a HS coaching job in 1951 that he would have gone 12 years without coaching.
