Teams were shooting around 40% in those days. Given our poor shooting this year, I became interested in how it compared to earlier years. I went to Jon Scott's site and dumped the yearly stats into an excel spreadsheet:
UK's trend line reflects the national average of most schools. Shooting improved steadily from the early days to the late 1960s. It leveled off and peaked in the 70s and early 80s. After that, the 3 point shot was introduced in 1986, and the overall percentage went down slightly.
It's interesting how the technique of shooting has changed and improved over the years. In the early days the two-handed, flat-footed, set shot from the chest was used. Some players began experimenting by shooting over their head to avoid defenders. Then they began jumping up. Some famous coaches (Hank Iba) were opposed to the emerging jump shot. They believed accurate shooting required both feet on the ground and also thought shooting up over defenders detracted from the strategy of the game.
Have you ever looked at the list of NCAA champions and seen Wyoming as 1943 champion? Wyoming? There is a reason for that. They had a 5' 10" guard named Kenny Sailors who was the first player to perfect the one-handed jump shot.
Sailors passed away a few years ago, but a documentary was made about him before he died. It's a GREAT story for any fan of basketball history! Highly recommended! His one handed jump shot was as pure and perfect as anyone's today.
