Prosecutors believe Aaron Hernandez's 2015 prison phone conversations with NFL star Mike Pouncey could help prove Aaron murdered two people in 2012.
TMZ Sports has obtained court docs in which prosecutors are asking the judge in the case to admit transcripts of the phone calls as evidence in Aaron's double murder trial.
Essentially, prosecutors believe the calls show Hernandez uses the word "try" as a way to describe being disrespected ... and talks to Pouncey about how he responds when someone "tries" him.
Officials say Hernandez felt the victims in the homicide case were "trying" him before he shot them to death later that night.
