A Hall of Fame quarterback reportedly believes Browns quarterback Johnny Manziel isn’t a lost cause just yet.

In a story published Saturday by USA Today, former Cowboys standout Roger Staubach praised Manziel’s skill level.

“If he really truly gets his life back on track, his talent is Russell Wilson-type talent,” Staubach told USA Today‘s Jim Corbett. “So size isn’t the overwhelming issue for him when you have Russell and Drew Brees winning Super Bowls at the same size.”

However, Staubach suspects the 6-foot, 207-pound Manziel has relationship-mending to do with his teammates.

“You have to be mentally tough and you have got to be a leader. And you have to transfer that to your teammates,” Staubach said of a quarterback’s role, according to USA Today. “And I think Johnny lost the confidence of his teammates because of his personal issues. He has to get that back.”

Such are the caveats that come with even taking an optimistic view on Manziel’s future. First — and most importantly — he must successfully address his health. Then comes everything else — his preparation, his play, his rapport with teammates.

Nevertheless, Manziel could do worse than an endorsement from Staubach, the 1963 Heisman Trophy winner.

“I read where the Browns have already given up on him,” Staubach told USA Today. “He’s a first round draft pick. I don’t think you can give up on him that quick, can you?”

Staubach has a point about Manziel, the 2012 Heisman recipient.
