Continuity mistake: In the beginning when Mox comes downstairs and is talking to his father at the breakfast table his Father has his tie over his shoulder, then the little brother comes in the room and knocks the tie off his shoulder, then the camera goes back and forth and the tie is on shoulder, then off the shoulder. (00:03:36)
Continuity mistake: In the beginning when Lance is walking out of his house, a wide shot shows the screen door is shut. When it cuts to him he's walking out from inside the house and the screen door is already open. (00:04:35)
Continuity mistake: When Billy Bob is going to talk to Lance at the beginning, he walks from a point about 5 feet in front of the truck instead of around the front of the truck. (00:04:50)
Continuity mistake: When Tweeder says he's going to have carnal knowledge of Billy Bob's pig, he has his arm on BB's shoulder so that BB's number was behind his arm. It switches shots and the numbers are in front of Tweeder's arm. (00:05:50)
Continuity mistake: In the shots at the beginning when driving to school Lance and Tweeder switch positions many times. First Lance is in the rear driver's side corner and Tweeder is in the front passenger's side corner. Then Lance is in the same corner and Tweeder is in the rear passenger's side corner. Then in the final shot Tweeder and Lance have switched corners. (00:06:00)
Continuity mistake: When Tweeder is showing Mox the endzone dance, in the background you can see Lance getting shot up with steroids. When Mox looks into the room he's getting shot up again. (00:10:10)
Continuity mistake: After the first completion to Tweeder the scoreboard says the ball is on the 38 yard line. An incomplete pass is the next play and all of a sudden they are on the 20 yard line. (00:10:55 - 00:11:45)
Continuity mistake: In the first game Lance completes a pass to Tweeder down near the goal line (the ref waves his hands above his head which means completed pass and runs to mark the spot). The next play Lance passes the ball straight out into the flat to the running back, but it's at the 30 yard line. (00:10:55)
Continuity mistake: In the first game when Billy Bob says, "We're punching it in for 6," the quarterback (to BB's left - BB plays right guard) is wearing number 5. Lance is number 7. (00:11:45)
Continuity mistake: When the coach is yelling at Moxon and he's grabbed him by the facemask, he has an overhand grip in one shot and an underhand grip the next. (00:20:30)
Continuity mistake: In the game after Billy Bob passes out, the defense stops the opposing team and lance runs out onto the field. Billy Bob is already in the huddle. The next cut shows Coach Kilmer telling Billy Bob, who is on the bench taking oxygen, that he "needs him for one more series." (00:29:05)
Continuity mistake: When Lance gets hurt, the guy who tackled him is partly laying on him, but in the next shot he's not on him at all. (00:29:50)
Continuity mistake: On Moxon's first play they start on their 25 yard line (huddled on the 15 and went 10 yards when the huddle broke). The announcer says he throws a 40 yard pass, which would put the catch on the 35 yard line. When Tweeder caught it he only got about five yards running, so when it couldn't have been on the 16, where Tweeder got up, or like the scoreboard said a second later. (00:32:10)
Continuity mistake: When the cop car pulls up on Moxon (with Tweeder driving) it says "West Canaan Sheriff," a local law officer. The next day the cop in the restaurant says "They stole a state trooper car" which is a totally different law organization. (00:40:15 - 00:42:35)
Continuity mistake: When Tweeder comes in the car he pulls in almost perpendicular to the sidewalk. Moxon stands next to the car when he gives the girl his jacket. When the car leaves, it's no longer perpendicular to the sidewalk and Moxon is standing about 5 feet from it. (00:40:45)
Continuity mistake: The announcer says that Moxon just had a 40 yard scramble when playing the Broncos. It cuts to the scoreboard and the ball was only on the 20 yard line. (00:44:25)
Continuity mistake: In the game against the Wildcats, the first shot is of the team on the 45 yard line. He rolls back about 10 yards and gets sacked. The next shot is of the scoreboard and it says the ball is on the 15, when it should be on the 35. (01:04:00)
Continuity mistake: In the first "Oopdy Oop" play in the game it has Moxon looking to his left, then cuts and he immediately throws right without ever turning. (01:32:10)
Continuity mistake: In the first "Oopdy Oop" play it has Tweeder being tackled. It cuts and Tweeder is falling down again in the next shot. (01:32:10)
Factual error: Right after Tweeder scores the first TD in the second half against Gilroy, it shows one of the Gilroy players on the bench take off his helmet while on the field and throw it down. This should be an unsportsmanlike conduct penalty as well as a too many men on the field penalty against them. (01:33:00)
Answer: There's no rule in any sport, at least none that I could find, that requires a team to have, or listen to, a coach. Obviously in most cases it's a good idea, but if the coach were poor and/or working against the interests of the team, the players wouldn't be breaking any rules by simply ignoring them and listening to someone else.
