The 2019 NFL campaign was, uh, not kind to the Cincinnati Bengals. They finished with the worst record in the NFL at 2-14, their quarterback situation was horrendous, A.J. Green was out, and their defense was an unmitigated disaster.

But luckily, when you are the worst team in the league, you end up with the No. 1 overall pick.

The Bengals used that selection to take LSU's Joe Burrow, considered by some to be the best quarterback prospect we have seen since Andrew Luck in 2012. Heck, some have gone as far as to say he is the best signal-caller prospect we have seen since Peyton Manning back in 1998.

Still, even with the addition of Burrow, Cincinnati has a lot to work on moving forward.

Here are the biggest questions for the Bengals entering 2020:

3. Can A.J. Green stay healthy?

Many wondered if Green would even be on Cincinnati's roster going into next season. Still, the Bengals decided to keep him around in order to provide Burrow with a reliable veteran target.

The problem is, Green has had a whole lot of difficulty staying on the field in recent years.

Since 2016, Green has played in just one full season, which came in 2017. In total, he has played in 35 games over the last four years, and he did not play at all in 2019.

When healthy, there is no denying that Green is one of the NFL's best wide receivers, and along with Tyler Boyd, he helps comprise one of the better receiving duos in football.

But he actually needs to avoid injury to make that happen.

2. Can the defense not be terrible?

The Bengals' defense allowed 393.7 yards per game in 2019, which ranked 29th in the league. Unfortunately, it's hard to envision Cincinnati being that much better in that area in 2020.

Cincy did bring in defensive lineman D.J. Reader on a four-year deal in free agency, so he should help solidify the front four. The club also went defense with four of its last five draft picks between rounds three and seven.

However, we still don't know where the pass rush is going to come from, as the Bengals totaled just 31 sacks this past season and haven't really done much to rectify that problem throughout the offseason. The secondary also remains a mess.

Perhaps Cincinnati will be slightly improved on the defensive side of the ball in 2020, but if the Bengals end up being anything more than a bottom-10 defense in the NFL, I would be surprised.

1. How ready is Joe Burrow?

Burrow is coming off of arguably the greatest collegiate season ever for a quarterback, throwing for 5,671 yards and 60 touchdowns en route to leading LSU to a national championship.

But is he ready to step in and reverse the culture in Cincinnati?

Here is the deal: he has some weapons. Green and Boyd are two excellent receivers, and Joe Mixon is a fine running back. The Bengals also took Clemson wideout Tee Higgins in the second round of the draft.

However, on the other side of the coin, Cincy's offensive line is miserable, and the team doesn't really have much at tight end.

Perhaps Burrow's supreme talent can overcome the Bengals' deficiencies, but as good as was at LSU, entering the NFL with a squad that just won two games is a different animal.
