Two-time MVP Kurt Warner accomplished numerous milestones over his 12-year career. So if anyone knows how to be successful and achieve longevity in the NFL, it's Warner.

The retired Arizona Cardinals' quarterback had nothing but praise for former Arizona State quarterback Brock Osweiler, who he believes has the potential for a prosperous career in the NFL.

"I am just excited about him as a kid," Warner told Arizona Sports 620's Doug and Wolf Friday. "I think he's got a big ceiling. I don't think he's reached his full potential yet and so I think the sky is bright for him in regards to what he can be."

One of the more refreshing qualities that Osweiler possesses is his thirst for knowledge. Warner said Osweiler worked out with San Diego Chargers quarterback Phillip Rivers this winter and Rivers came away impressed by how open the former Sun Devil was to learning in the classroom and asking questions.

"I think that bodes well to have a young kid that doesn't think he knows it all," Warner said.

Still, Warner says it's hard to gauge whether a quarterback will have success in the NFL based solely on talent alone.

"There's so much at the quarterback position that's really mental and the ability not just to throw the football 50 yards down the field and be accurate with it, but it's the ability to be able to read things, see things and adjust to things and react quickly," Warner explained.

Warner interacted with Osweiler at the NFL Scouting Combine and feels he does have a good head on his shoulders but he's going to have to continually look for ways to improve and re-invent himself if he hopes to have staying power in this league.

"It's going to take a lot of work and he's going to have a grow as player I think to become a great player in the NFL," Warner said.
