Although López was said by some to have been the Spanish version of John Stockton, his game was often described as more similar to that of Steve Nash and Tony Parker.

In 1998, at 18 years old, López began his professional career with Joventut Badalona in the Spanish ACB League.

Later, during the summer of 2005, he signed with the Spanish local team Akasvayu Girona, which finished 7th at the end of the 2005–06 ACB season.

Lopez' final NBA game was played on 15 February 2005 in a 95 - 102 loss to the Los Angeles Lakers.

López was named, along with Juan Carlos Navarro, to the senior Spain national basketball team that participated at the 2000 Summer Olympics in Sydney, Australia.
