Jameis Winston responded to all the lingering questions with some bold answers.

According to Winston, the character concerns that dogged him at Florida State are history. The comparisons to Johnny Manziel are irrelevant. The supposed throwing shoulder injury is a non-issue. And anyone who thinks the 2013 Heisman Trophy winner can't be successful in the NFL is sorely mistaken.

Now the league must determine whether they believe the Florida State quarterback can pull it off.

"What I do tell them is, 'I have to earn your trust,'" Winston said. "I can't talk about situations or anything like that in the past but what I can do is prove to them and let you watch me grow into being the face of your franchise."

ESPN reported that doctors at the combine were conducting additional tests on Winston's throwing shoulder. He said he would throw during today's workout.

"I had the MRI, just like everybody else. I've been playing football since I was 4 years old and the shoulder's been fine," Winston said.
