SUPPORT IS KEY TMZSports.com
James Conner -- an Arizona Cardinals superstar who's beaten cancer -- is offering up advice to Randy Moss as he faces his own battle with the disease ... telling TMZ Sports the Hall of Famer should make it a priority to lean on his loved ones.
Conner was diagnosed with Hodgkin's Lymphoma back in 2015 when he was a college running back at the University of Pittsburgh ... but he ended up beating it, and he's since gone on to have a hell of an NFL career.
