Patrick Beverley's legal team is disputing the allegations that led to his felony assault arrest ... with his attorney claiming the ex-NBA player's sister's side of the alleged incident is not accurate.
Letitia Quinones-Hollins tells TMZ Sports the details laid out from Beverley's 15-year-old sister to cops in the probable cause affidavit were "given at a time when emotions were high" and don't tell the truth or the complete story.

"Patrick is not a violent man and was not violent that night," Quinones-Hollins said Tuesday.
