Perhaps the first name that came to mind when "what if" was mentioned was D.Rose. He was a very good basketball player, a very good athlete. Despite serious injuries, he managed to become one of the legends of the NBA.
Even though he never became a champion, we will always remember him and his playing style very well.
The shoes that Adidas released on his behalf were among the best shoes of the time. In recent years, he has been able to do great things in the NBA despite his age. Time passes and we get older
True, there are a lot of what if for DRose, specially if he didn't have that career ending injury. Youngest MVP and on the brick to have one of the best season and player in the Bulls uniform since MJ himself and there's a lot of promise. Specially him and Lebron are in the same division that time and they have a lot of great battles.
What if he did bring a ring with the Bulls, it could really change what is the East during his prime. It's really very unfortunate that he had to earn his career. But at least during his peak, and maybe up to this day, we will not see such player which pure talent like him.
