When the tall player is recruited off the basketball court, the basketball hoop is portable, with a breakaway rim. Marshall's basketball gym has the same rims. Breakaway rims were invented after 1981, when Darryl Dawkins of the Philadelphia 76ers broke two backboards in two nights.
Coach Lengyel and President Dedmon talk in a basketball gym about getting the NCAA to let them play football. The court has a three-point line, which the NCAA adopted in 1983, and the National Federation of High School Rules adopted in 1984.
One scene includes a train in the background. One freight car has a Conrail logo, founded in 1976. Another freight car has a CSX logo, founded in 1980. The lead locomotive is a modern 'comfort cab' (also called Canadian Cab or Safety Cab) with a current Union Pacific paint scheme. Union Pacific had no trackage east of Kansas City in 1971, and run-through locomotives from other railroads were not common in the early 1970s.
When Nate Ruffin and a varsity player talk on the roof of a campus building, the new Library and Football Stadium, built in the 1990s, can be seen in the background. The stadium appears only once, and is edited out of subsequent shots. It doesn't appear in the DVD version.
When a crowd of people walk past a residence to the first football game of the 1971 season, one woman has a tattoo on her left ankle. A woman with visible tattoos was very rare during that era, especially in an ultra-conservative town like Huntington, WV.
When Jack Lengyel and Red Dawson review the black-and-white 16mm footage of the "Veer" plays, the footage includes large square pixels, indicating that it was blown-up from a lower-resolution digital source. That particular optical flaw is specific to the Internet, and is most commonly seen in low-resolution user uploaded videos. In 1971, blowing up low-resolution film would result in grainy footage.
All the characters, including Coach Lengyel, consistently pronounce Wooster College's name as though it rhymes with "rooster" - whereas the college's (and the town's) name is actually pronounced by residents and students, like "Worcester" as in Worcester, Massachusetts (or England), i.e. "wuss-ter."
After recruiting the new players, the coaches talk about having a quarterback named John Cady. When they go to the field to practice, Lengyel asks about his options for quarterback, and no one mentions John Cady.
Coach Lengyel talks out of the right side of his mouth. In one scene, while visiting West Virginia University, the camera shows his reflection in a trophy. He starts talking out of the left side of his mouth, then switches, as if he realized his mistake. When Coach Lengyel first looks at the trophy, he talks out of the side of his face. In the next shot, Lengyel's mouth is flat.
In spring 1971, Jack Lengyel and Red Dawson approach WVU football coach Bobby Bowden for use of his "veer" formation. Dawson says the two schools "are rivals." Bowden agrees to help, saying "We don't play y'all this year." WVU and Marshall are basketball rivals; they hadn't played each other in football since 1923, and didn't again until 1997.
When Coach Lengyel and President Dedmon talk about getting the NCAA to let them play football, Dedmon mentions that he will be married 25 years in May. Dedmon was 39 in April 1971, which would mean he got married at 14. Even in West Virginia, that's not likely.
When Lengyel runs out of the house chasing his son and sees Marshall fans walking to the first 1971 home game against Xavier, pink and white blooms are visible on the dogwood trees in the background. The game was played September 25, 1971, when the dogwoods would not be in bloom.
