Is that technically pidgin? I thought pidgin was a simplified version of language used expressly for communication between speakers that don't understand each other. Is it still pidgin if neither one understands full sign language?
If the Deaf team are using sign language to communicate with each other, then no it is not pidgin because American Sign Language is a language. Pidgin is a lingua franca like Gestuno (International Sign) and Esperanto.
EDIT: If you are talking about Deaf Team and Hearing Team (people with hearing ability for those folk who are not familiar with Deaf communities jargon) attempt to communicate with each other without sign language, then yes it can be a pidgin. If the Deaf Team itself communicating with their teammates, then it is not a pidgin because they switch to their native language to express.
As far as I understand, Esperanto would not be considered a pidgin as it's an artificial, designed language. Pidgins are natural languages that form in order to facilitate communication in multilingual environments.
