Other mistake: When Adam comes in and says "when I woke up this morning, the pain was gone", Connie is mouthing his lines behind him.
Plot hole: In the Cowboys' last possession of the final game, Spike makes a long run before being stopped on the goal line. The Cowboys' next play is a run up the middle. The Little Giants stop the run and the Cowboys lose possession, but since that was the first possession of a new set of downs, the Cowboys would have three more chances to score.
Revealing mistake: Signs for Baltimore based businesses are clearly visible in the stands, such as "Sheraton Inner Harbour" and various Baltimore banks.
Revealing mistake: In the fight between Julie and Ned, when she does the last kick to take him down, it's obvious that she doesn't actually kick him.
Continuity mistake: In the scene when Nick Nolte is arguing in the parking lot, he unlocks his car door, but his window is rolled down in the same scene.
Continuity mistake: In the last game of the movie you can see that Ray Mitchell (Angel Player) hits a home run to tie the game. If you look you can see that the home run ball goes over the fence and out of the stadium but then after they change cameras to Ray and then back to where he hit the home run it shows a man with the ball in his hand as if he caught it.
Continuity mistake: At the final fighting scene (David Sloan vs.Tong Po), you can see that Tong Po's hair (a half shaved head with only a ponytail on it) is as fake as it can be: everytime when he moves his head a bit to rough around (sweeping his ponytail around while fighting) clearly shows that he's wearing a special kind of wig attached to his head. That 'wig' is so badly attached that it looks like he's got rimples on the back and on top of his head.
Factual error: Under the rules of Major League Baseball, a team owner cannot also serve as the team's manager; it constitutes a conflict of interest.
Continuity mistake: During the final basketball game, when Shep makes a finger roll for a layup, his jersey and 15 are backwards.
Continuity mistake: When the doctor is telling Al her diagnosis, the pencil on the clipboard disappears and reappears as the camera angle changes between her and Al.
Continuity mistake: In the scene where Lane, Tuff and Cody are talking about Leffow right before Lane rides there is no leather strip around Lane's neck to tie his glove on with. In the next shot he has the leather strip around his neck. (00:28:35)
Continuity mistake: When Ernest is messing with the pipe in the locker room the toilet seat in the middle stall goes from being up to down and back up again.
Factual error: In one scene Cobb and the sportswriter doing his biography are driving across the country to get to the baseball Hall of Fame. They are stopped next to some railroad tracks fixing a flat tire, and a train goes by that has Burlington Northern markings (BN). Burlington Northern didn't come into existance until ten years or so after Mr. Cobb died.
