A player is drafted by the Detroit Pistons, they don’t immediately score 20 points per game, and after a few seasons fans are ready to move on from them just because they don’t think they can be a long term piece for the team.
In these conversations, a point that’s seemingly always brought up is something to the effect of said player lacking the ability to be a top scoring option for their team. That they can’t lead the team to a championship.
So whether it’s trading them away or deciding to not extend them, fans are ready to move on from players after two or three seasons.
