In the beginning of the film, Coach Don Haskins is coaching a girl's basketball game. A standard 5 on 5 game is depicted, however up through the 70s (and in some states 80s and even 90s) High School Girls Basketball was played 9 to a team with the players assigned specific zones that they could not leave at any time. This was also the college rule until 1971.
The final game with Texas Western and the University of Kentucky is televised by NBC. The "Snake" logo from 1959 is shown with the 1979 "Proud as a Peacock" logo. The movie takes place in 1966, so the 1956 "Living Color" Peacock should have been used. Anyway, at the time the Peacock wasn't the logo of NBC and only the "NBC Snake" would've been used. In either case, NBC didn't televise the NCAA Championship until 1969.
When Texas Western is playing Kansas for the Midwest Finals, there is a KU banner hanging from the rafters of the ceiling of the auditorium. The banner depicts the KU Jayhawk facing the right. That is the current KU logo, but in 1965, the logo would have been facing left.
Coach Don Haskins says, when offered the job at TWC, that he's glad to have a job offer in "Division 1". The NCAA didn't have divisions until 1971. In 1965, schools were divided into a "University Division" and a "College Division".
2 1/2 minutes into the film a shot appears with the logo, "Texas Western College, El Paso, Texas". A large satellite dish appears on a rooftop toward the left edge of the frame. Several of the buildings in the background are clearly modern.
When Bobby Joe Hill is running the steps and Coach Don Haskins was yelling at him you could see behind Coach Haskins in the end zone was white with UT and MINERS painted on it, implying the acronym UTEP Miners. In 1966, the end zone was actually blue and said "EL PASO, TEXAS".
The close-up cutaway shots of the scoreboards in several sections of the movie do not match the scoreboards used in the wide shots or action shots. Most of the time, the action shots use a modified Nevco Model 2400. The cutaways are sometimes a TransLux Fair Play/Fair Tron scoreboard, sometimes another brand scoreboard all together. The Nevco 2400 can be programmed to display a zero in the minute column when there is less than a minute of play left. In the movie, one shot shows the scoreboard display ":55" with no 0 for the minutes and later in the same scene "0:02" with a 0 in the minute column.
After Lattin picks up his fourth foul in the Championship game, Coach Don Haskins takes him out of the line-up. But after the next basket by Texas Western, you see him running back down the court. it's not until later, with two minutes to go, Coach Haskins puts Lattin back in the game.
During the championship game against Kentucky, #44 hurts himself
and must leave the game. A few minutes later he is announced as out for the game with the leg injury, but he is seen in several shots in the second half as being on the court and playing.
During the grueling "AM" practice, Coach Don Haskins is seen wearing a white shirt while mocking the players about the previous night. In other frames of the practice, he is seen wearing a black shirt. When he goes back to his room and kisses his wife, the shirt is white again.
The sequence of scenes where a player gets beat up in a restaurant bathroom, the team returns to their hotel room only to find it trashed and racial things written on the walls, and the fans at the team's one loss of the year where they berated them with racial slurs never happened. On the contrary, the opponent, Seattle University, had four black starters of their own.
When one of the players gets beaten up it appears to be Christmas time and another character tells a young boy "Merry Christmas." At the time the team was supposed to be 17-0. In 1966 the schedule didn't even start until Dec. 1, so the team could not have played seventeen games by Christmas.
Flipped shot: Before the national championship game begins, Coach Rupp shakes hands with one of the officials. They shake Left hands and Coach Rupp is approaching from the Texas Western bench direction.
