Oscar Hernandez, no relation to Aaron, has pleaded guilty to charges including gun conspiracy and lying to a grand jury.
Oscar Hernandez shipped several guns from Florida to Aaron Hernandez in Massachusetts two months before the then-star tight end killed a man in 2013. He did not supply the murder weapon.
His lawyer says his client was awed by a celebrity and asked the judge to sentence him to 1 year and 1 day, longer than he has been in custody.
Prosecutors want a sentence of 2 years and 8 months because of the seriousness of his crimes.
