NBA's three biggest disappointments: Is rookie teetering on 'bust'?

The Pistons have also struggled to find a second option for former No. 1 overall pick Cade Cunningham. Second-year guard Jaden Ivey looked to be that player last season when the Purdue star averaged 16.3 points and 5.2 assists in 31.1 minutes, but under new head coach Monty Williams, Ivey's minutes have dropped to 23.1 per game. 

Ivey is averaging only 11.4 points and 2.9 assists and has seen his starting job go to Killian Hayes, who has had his own struggles this season, averaging 9.7 points on 42.5 percent shooting from the field. That's below the league average of 44.5 percent for point guards.

"When you lose this many games, you got to make changes," Williams said on the roster adjustments, per ESPN's Tim Bontemps. "We're not going to leave any stone unturned."

With 10 of their next 14 games against teams with winning records, the Pistons could sink even deeper in the conference. Perhaps they'll challenge the Philadelphia 76ers' league record for most consecutive losses (28, spanning two seasons).

Scoot Henderson teetering on bust?

The No. 3 overall pick is struggling, averaging 9.2 points, 4.2 assists and 2.6 rebounds and shooting miserably (35.1% field-goal percentage) for the Portland Trail Blazers.

Questions about the 19-year-old's shooting ability popped up before the NBA Draft. The thinking, however, was the 6-foot-3, 202-pound guard could use his otherworldly athleticism to consistently attack the basket. Henderson, however, is averaging just 1.9 free-throw attempts per game.

The former G League Ignite star started the first five games of the season before suffering an ankle injury that forced him to miss the next nine games. Upon returning on Nov. 22, Henderson was moved to the second unit, which is less than ideal for a No. 3 overall pick who was heralded as the new face of the franchise following the Damian Lillard trade.

There is plenty of time left in the season for Henderson to turn things around, but given how hyped he was, his performance thus far is disappointing. 

'Big Four' is floundering for Los Angeles Clippers

On paper, pairing Kawhi Leonard, Paul George and Russell Westbrook with one of the best playmakers in the league in James Harden is a match made in basketball heaven.

However, this "Big Four" has yet to find consistent success. Since acquiring Harden in a blockbuster trade on Oct. 31, the Clippers are 7-8 and 18th in offense, per Cleaning the Glass, a major disappointment for a team with four elite offensive talents.

Leonard, George, Westbrook and Harden need the ball in their hands to be the most effective, and despite efforts to create more ball movement, the Clippers frequently regress to "your turn, my turn" isolation basketball. 

"There’s not enough basketballs on the planet for this team, really," Clippers veteran forward P.J. Tucker said, per The Athletic's Sam Amick.

Individually, Leonard, George, Harden and Westbrook are among the most exciting players to watch in the NBA, but they must find success as a unit. 

Things are trending in the right direction for the Clippers, who are 7-3 since Westbrook volunteered to come off the bench, but at 10-10, the team has a long way to go to become a playoff contender.
