The Lakers were out of the playoff picture for most of the season. It took Kobe going insane to even get us in the playoffs. It doesn't matter if it was the same core or not. Everyone outside of Kobe and Shaq were done. Horry shot 31% from the field and .
058% from 3 and he was one of our best players. Fisher was trash, Fox was done and so on. The roster was old.
Look at the Heat after they won the ring in 06. They returned the same core the next season and how did that turnout?

Its the same thing that happened to the 03 Lakers.
The Lakers barely got past the Wolves. They were down 0-2 at one point. Our only shot at winning a ring that year was having both Kobe and Shaq going ham. But Kobe was playing on one leg (forgot why he was in Colorado?

) and Shaq had a foot injury that plagued him for the entire season.
