Factual error: Although the tie is obviously done for the purpose of the story, the fact is that Morris Brown would never be given high marks for their performance at the Big Southern Classic. This is a marching band competition, and they do little moving at all, let alone actually marching, changes of formation, etc. If anything they would rank last of all schools, if they weren't disqualified outright.
Factual error: When Devon gets a package from his father, the stamp on it reads "Atlanta" when it should be New York, where Devon's father is from.
Factual error: During Devan's audition to get onto the A&T drumline, Devan is using a Pearl Competitor CSD snare drum with a high-tension Remo K-Series Falam marching snare drum head with a black center dot. This snare drum head can only be used on snares designed for use with extreme-high tension heads, such as the Pearl FFX-1412 snares that the P1 and P2 drumline members use. If used on the Competitor CSD snare drum as Devan was, the lug casings and bearing edge could face possible damage and failure because of the extreme high-tension required for use by the Kevlar head.

Factual error: In actual band competitions, the band is rated on several different factors - one being the Drumline (the third of four songs in each performance is the "Drum Break"). However, the final decision will never be based on an encore performance by the Drumline. If two bands happen to tie (which is very unusual, especially for first place), there is no "tie-breaking" performance.
Factual error: During the scene at the first show that the band plays, the drumline finishes by playing a cadence at the end of the song. When the head section leader comes out to play his solo, Devon also plays with him. At the end Devon gets on his knees and starts playing a roll. There are two different camera shots of this, one where you see Devon's hands playing, and one of his upper body. Every time they show the shot of his upper body, his arms and shoulders are moving way too fast for the roll that he is playing on the drum. But when they show the shots of his hands playing, his arms are moving like they should when you play a roll.
Factual error: After Devon gets the package of tapes from his father he is sitting on his bed and he is about to practice. When that shot starts, he is twirling his drumstick and his fingernails are dark in color, but Devon's nails are actually light in color.
