2. Mark Jackson
Mark Jackson can be called many things, he thinks of himself as a leader, but ask anyone who was a fan of the Utah Jazz in 2002, and they'll tell you that he was nothing more than a sabotage. Jackson is famous for leading an attempted coup de tat against one of the greatest point guards of all time in John Stockton. He rallied the younger players, namely Deshaun Stevenson, and tried to force himself into the starting rotation.
It was never going to happen. He had declined significantly at his age and was barely good enough to be a rotational player. That didn't stop him from sowing dissent among the disgruntled bench players. The locker room became split due to Jackson's meddling, forcing teammates to choose sides.
Stockton never lost his spot, but despite the Jazz making the playoffs, he would eventually retire after losing to the Sacramento Kings in the first round. He cited publically it is harder to prepare for games at his age, but many in the know cited how the whole Jackson situation played out with Stockton being heartbroken that some of his teammates rebelled against him all for a player that kept getting traded for good reason.
When you're tied to forcing a legend to retire, you're almost always number one. Unless you make a legend retire, and are a franchise star.
