Miller has had his issues since entering the NFL, most notably a six-game suspension for violating the league's drug policy in 2013. He says people tried to count him out.
"I remember what it was for me when I was in a similar situation, it was the people around me that helped motivate me to get to the same Von that I was," Miller told the Morning News.
"(Manziel's) had people walk out on him. He's had people who have given up on him. I'm not going to be that guy. I've never been that guy. Johnny's my brother. I didn't play with him at Texas A&M, but he's my brother and we have a unique relationship. I'm here to help him no matter what it is. I'm tied to him, good or bad. You can't ever count anybody out and I think everybody who has counted him out is just wrong."
Manziel told TMZ last week that he was living with Miller. An ESPN source said Manziel is instead living with former Cleveland Browns wide receiver Josh Gordon in West Hollywood. Miller said, although they don't live together, he speaks to Manziel on Facetime daily. Miller said he is trying to help his friend get back on track.
"Just to remind him of who he is. The Johnny Manziel who I first met," Miller told the Morning News. "The fun-loving, outgoing Johnny Manziel who cared about everybody. Where he's at, it's hard to know what's up, down, right, wrong -- I've been there. And it was people like me who reminded me what was right and what was wrong, that's what I'm trying to do for Johnny."
