2019 NBA Playoffs: Which teams should be the most concerned right now?

After the first few days of the 2019 NBA Playoffs, which higher-seeded and “tough out” teams should be the most concerned?

The first round of the 2019 NBA Playoffs would be boring, they said.

Okay, so maybe some of the games haven’t been the most entertaining affairs, thanks to a couple of massive runs leading to a few uninteresting blowouts, but the series themselves have brought more intrigue than expected. With so many lower-seeded teams providing Game 1 upsets and challenging their heavily favored opponents, these matchups may be more competitive than expected.

The question is, which higher-seeded teams or projected playoff contenders are in the most trouble through the first four days of playoff action?

From the outright championship-caliber squads to a pair of lower-seeded teams that were either favored in the first round or expected to be a tough out, here’s a look at six teams — excluding the heavy underdogs expected to lose like the poor Detroit Pistons — that might have cause for alarm, ranked from the least concerned to the most in trouble.
