After the losing season at the start of the movie, Coach Bell travels to see Butch play a high school game. The college season outlasts the high school season by weeks to months. There is no chance that Butch's team is playing a home game after the college's regular season is over. There is a small chance that the coach could have gone to a State Tournament game to see Butch play, but even those tournaments are over before the college season ends. In addition, most high school players have signed a letter of intent early in their senior year making a recruiting trip in the early spring unrealistic. It is understandable from a pacing perspective why the film was shot this way. The coach has another losing season and decides not to let it happen again and goes after the Blue Chip players to be better next year. In the real world, he would have been making the recruiting trips (or his assistant coaches would have) much earlier, during the season and not after it.
