Sam Darnold is confident he can still become one of the NFL's best quarterbacks.

"As long as I know what we're doing, what the defense is doing, I'm confident I can be one of the best quarterbacks in the league," Darnold said.

Darnold has a 17-32 record as a starter in the NFL. The Carolina Panthers drafted Matt Corral in the third round and Matt Rhule also hasn't ruled out bringing in a veteran.

"What Sam has been through this offseason has been very hard," Rhule said. "Your back's against the wall. Everyone's kind of questioning whether you can do this or not. We've seen a guy who has shown up who has a little more edge to him. He's very, very focused."
