Fantasy basketball: 5 potential busts you should steer clear of

There are various reasons why players underperform in fantasy basketball, including the addition of teammates with whom a chemistry needs to be established, a history of health issues that are being overlooked, or a level of hype that can't realistically be met.

Here are five players you should be cautious about drafting this season:

SF/PF Jayson Tatum, Celtics

Tatum's ability to once again average 13.9 points and 1.6 assists per game could be in jeopardy. Tatum should be, at best, the third scoring option for the Boston Celtics behind Kyrie Irving and Gordon Hayward - the latter being an All-Star in 2016-17 who missed all but five minutes last season due to injury. Hayward has typically seen around 15 shots and plenty of play-making touches per game when healthy.

Tatum is still very valuable, and if he falls beyond the first 70 picks in your fantasy draft, there's no reason to pass on him. Someone in your league will take him earlier than that, however. Tatum could still put up solid secondary fantasy stats - made 3-pointers, steals, free-throw percentage - but don't expect a major leap in scoring.

PF Lauri Markkanen, Bulls

Coming off All-Rookie first-team honors, expectations were high for Chicago Bulls forward Markkanen, but his team's offseason moves combined with recent injury news have cooled his outlook considerably.

Markkanen won't be returning to the same situation that allowed him to put up 15.2 points and 7.5 rebounds per game as a rookie. Now, he'll have to share the frontcourt with Jabari Parker. The team also invested its No. 7 pick on big man Wendell Carter Jr., and Bobby Portis remains an important component in the rotation.

It was also announced in late September that Markkanen would miss six-to-eight weeks of action after an MRI revealed a sprain in his right elbow. That recovery timeline isn't necessarily a devastating blow to his season-long fantasy value, but a setback at this time of year could have the Finnish phenom playing catchup for most of the campaign.

PG Kris Dunn, Bulls

Another Bull makes the list, as point guard Dunn is in the same boat as Markkanen. Zach LaVine was held to just 24 appearances last year due to his prolonged recovery from an ACL injury. A ball-dominant scorer, LaVine will take touches away from Dunn. When active, LaVine was the team's leading shot-taker with 14.8 attempts in just 27.3 minutes per outing.

Dunn will likely still lead the Bulls in assists, but between LaVine's improved health and the team's offseason additions, his chances of repeating or improving upon last year's stat line - 13.4 points, six assists, 3.8 rebounds per game - are low.

At the very least, however, Dunn will provide steals. The scrappy guard ranked fourth in the league last year with two steals per game, behind only notable ball-hawks Victor Oladipo, Eric Bledsoe, and Jimmy Butler.

C John Collins, Hawks

Collins had some memorable, highlight-reel moments as a rookie en route to averaging 10.5 points, 7.3 rebounds, and 1.1 blocks per game. He also committed 4.3 personal fouls per 36 minutes, often forcing then-Atlanta Hawks coach Mike Budenholzer to relegate him to the bench early and often. You can't contribute if you can't stay on the court.

Collins will have to adapt to new pick-and-roll partners in the Hawks' backcourt. Dennis Schroder is gone, while oft-injury Jeremy Lin and rookie Trae Young are in. You just don't yet know what you're getting from either point guard, and it's unclear how much scoring Collins can create for himself at this stage in his career.

FantasyPros ADP: 56 Overall, C17

SF/PF Kyle Anderson, Grizzlies

As one of the many role players churned out by the San Antonio Spurs over the years, Anderson became somewhat of a darling in the basketball nerd community thanks to his glacial pace and old-school interior game, which stands in stark contrast to the style of play favored in the league today.

Now with the Memphis Grizzlies, Anderson is destined to be the proverbial glue guy - someone more valuable in real life than in fantasy.

Even in his breakout fourth season in the league, Anderson only put up 7.9 points, 5.4 rebounds, 2.7 assists, and 1.6 steals per game. While he shot a respectable 52.7 percent from the floor, he did so with fewer than one 3-point attempt per game. He's essentially Joe Ingles with a weaker assist rate and no real indication he'll boast an above-average 3-point stroke in the near future.
