As of right now, the 2019-20 NBA campaign is slated to resume in late July. Of course, there has been some pushback from some of the players, but for now, let's operate under the assumption that the season will resume.

Only 22 teams will be invited to Disney World for the resumption of the season, and let's face it: of those 22, only a few have a realistic chance at winning a championship.

The Boston Celtics are one of those second-tier title contenders that could make a run if everything breaks right.

So, here are the three biggest questions for Brad Stevens' squad as they prepare to head to Orlando.

3. How much will the Celtics' bench contribute?

While Boston has been one of the top teams in the NBA all season long, its production has been rather top-heavy.

The starting lineup of Daniel Theis, Jayson Tatum, Gordon Hayward, Jaylen Brown and Kemba Walker has been brilliant, but once you get past Enes Kanter and Marcus Smart on the bench, it's a crapshoot.

Yes, star power wins championships, but it's also vital to have strong depth, something the C's currently lack.

Brad Wanamaker has been solid for what he is, but the fact that the Celtics are pinning their hopes on a soon-to-be-31-year-old who barely played any NBA ball before this season speaks to how thin their bench truly is.

Rookie Romeo Langford has emerged as a terrific wing defender, but relying on him for offense seems unrealistic at this point. The same can be said for fellow rookie Grant Williams.

The good news is that the long layoff should have allowed Robert Williams to get healthy, but overall, Boston's lack of a bench could end up being its ultimate downfall.

2. Can Jayson Tatum maintain his previous torrid pace?

You may have forgotten considering we haven't seen basketball in three months, but Tatum was ascending into the upper echelon of scorers in the NBA in February and March.

The 22-year-old is averaging 23.6 points on the season and posted 30.7 points per game in February on a ridiculous true shooting percentage of 63.7 percent.

Between Feb. 5 and March 10, Tatum racked up nine 30-point outings, including a 41-point outburst against the Los Angeles Lakers on Feb. 23.

Obviously, Tatum is someone who did not benefit from the hiatus, as it may have disrupted his rhythm.

The good news is that Tatum is surely talented enough to pick right back up from where he left off, but there is also no question that some rust may need to be shaken off first (like just about everyone else).

1. Has Kemba Walker's knee healed?

Unlike Tatum, who was possibly hurt by the league's suspension, Walker needed it. Badly.

The Celtics' prized free-agent addition was dealing with a rather balky knee in February and March, a problem that was compounded when he played significant minutes in the All-Star Game.

Walker's impact on Boston this year has been palpable. Not only has he been great on the floor, but his leadership in the locker room has been night and day compared to what Kyrie Irving provided last season.

Hopefully for the C's, all of the extra rest has given Walker's knee an opportunity to heal.
