- Many of the characters in this episode were named after characters in The Bad News Bears series of movies. The movies were about a team of misfits playing little league baseball.
- The mentor/apprentice relationship between the unsubs in this episode is similar to the dynamic in How To Be A Serial Killer, in which Matthew Gray Gubler played the apprentice. In that movie, as in this episode, Gubler's character wore a baseball cap. Some of the scenes with Morgan patting Reid on the shoulder while coaching him mirrored the interactions between Gubler's character and the serial killer mentor in that movie.
- Possibly meant to be Joseph Duncan III, but the BAU's description of him doesn't match common facts about him
