I've been trying to think of some examples of players who performed poorly in limited opportunities over the first few years of their career, and then find a different team and take off during the middle years of their career. I'm looking for elite level talent, or guys who could start or play a significant role on a championship team.
Demarre Carroll, Danny Green, Kyle Lowry, Hassan Whiteside, Kris Middleton, and Aaron Afflalo, Robin Lopez and Marcin Gortat played well in limited minutes before they sign with a different team after their rookie contract.
Of those players, obviously Demarre Carroll and Kris Middleton both bear the most similarities in position and play style.
Carroll was drafted 27th in 2009 by the Grizzles. He was considered a tweener forward who was athletic, but not skilled enough for either position. From 2009-2012, he played for four teams, was very inefficient, and his minutes were spotty. Playing for Utah, he developed consistency and some efficiency, and that transferred to the Hawks when he signed a two year deal with them.
Middleton was drafted in 2012 (the same year as Jones) 39th overall by the Pistons. Although his numbers were decent that year, he fell out of grace with the coaching staff and was traded to the Bucks in the off-season after his rookie. He was listed as a power forward for part of his early career, but his perimeter skills developed and his 3 point shooting gave the Bucks the flexibility to play him on the wing.
It has been noted that Jones is a tweener forward, silky smooth athlete, and widely skilled in many areas of the game. However, he does not have any true strength, gets pushed around a bit, and lacks consistency.
There is precedent for players of Jones' skill and athleticism to develop into elite players, but there is also precedent for players like Jones to fade out of the league. Any way you look at it, being in a stable organization and playing for a heady coach like Stevens who employs a positionless style of basketball is the best place for player like Jones to develop.
I could argue that Jones' development was hurt by the Thunder's rigid, position-based, iso-heavy system.
