The Carolina Panthers had one of the most interesting 2018 seasons of any team in the league.

They started 6-2 and were getting a ton of buzz, and then completely fell apart over the second half of the season.

There were rumors that head coach Ron Rivera's job would be in jeopardy, but the team ultimately elected to keep Rivera and most of the staff.

It's a crucial offseason for the Panthers, and here are three burning questions they'll have heading into it.

3. Is Cam Newton fully healthy?

Newton's health is the most important thing for the Panthers this offseason.

Newton didn't look right over the second half of the season, and the team eventually shut him down for the final two games of the season as he dealt with a lingering shoulder injury.

After the season, it was revealed that Newton had undergone another surgery on the same shoulder had had surgery on in early 2017.

Newton's injury was the main factor in the Panthers' collapse in the second half of the season, and if he's fully healthy they should be able to compete for the NFC South crown next year.

2. Will they add receiver help?

Even if Newton is healthy, he won't be able to do it all by himself.

He needs help from his receivers, and the Panthers need to upgrade what they have around him. Devin Funchess, D.J. Moore, and Curtis Samuel are all capable of fitting different roles, but none of them are ready to be a true number one receiver.

The Panthers' leading receiver last year was Christian McCaffrey, a running back.

That isn't sustainable, and the Panthers should look into trading for one of the many high profile receivers who are available.

1. Can they get Greg Olsen back to his previous level?

If they aren't going to add a big-name receiver, they'll need Olsen to return to his previous form.

Olsen was one of the best tight ends in football until the past couple of seasons. He hasn't topped 300 yards in either of the past two seasons as he's dealt with crippling injuries that knocked him out for extended periods of time both years.

Olsen flirted with retirement due to the injuries, but ultimately opted to return for 2019.

He says he still feels like he can be one of the best tight ends in the game once his foot is fully rehabbed, and if that's true the Panthers' offense will be back on the right track.
