Former Chicago Bulls star Scottie Pippen is good at selling books. Pippen continued his tirade against Bulls legend Michael Jordan on Monday, questioning whether Jordan's flu game was that impressive.

Pippen was asked about playing through a back injury during the 1998 NBA Finals against the Utah Jazz. Pippen said he would not have played if the series went to a Game 7 due to a herniated disc. The Bulls won the series in six games, making that a non-issue.

The conversation then turned to Jordan's flu game. Pippen made a direct comparison between the two ailments, saying, "I don't see many bad back games, but I do see flu games. Flu. Come on."

Pippen gutted out the back injury during the 1998 Finals. During the first four games of the series, Pippen averaged 20 points. In the final two games, that figure fell to seven points. Pippen played 45 minutes in Game 5, but his playing time dropped to 25 minutes in Game 6, a sign his back was hurting.

Jordan's flu game came a year earlier. In Game 6 of the 1997 Finals, which also came against the Jazz, Jordan scored 38 points to lead the Bulls to a win. Jordan had to be carried off the court by Pippen. Jordan later said playing through the flu was, "Probably the most difficult thing I've ever done."

Scottie Pippen continues to take aim at Michael Jordan, Bulls

Pippen's comments shouldn't come as a surprise. Pippen started going on the attack in June, taking aim at Kevin Durant, Doc Rivers and Ben Simmons. Pippen also ripped former Bulls coach Phil Jackson, calling him a "racist."

Jordan wasn't spared from that criticism. Pippen questioned Jordan's antics in that interview, suggesting Jordan played things up for the cameras. He also took Jordan to task over "The Last Dance," saying Jordan made the program all about him.

Pippen's new book, "Unguarded," was released Tuesday, so Pippen can take a break from the bitter, bridge-burning interviews for a few weeks.
