Yep, you know they didn't win the first 3 years he was there, right? you know they made it as far as the Conf Finals once, right? you know they lost 4-1, 4-0 and 4-0 in those 3 postseasons, right?
San Antonio won 2 titles while Shaq was a Laker so they didn't run away.
SA became this great run organization after they got Duncan, last I checked they weren't competing for titles pre Duncan.
Kidd chose to play in NEW JERSEY, NJ is NOT NY. The Nets were one of the worst franchises the sport has ever seen playing in front of no fans every night(much like Miami prior to Shaq and post Shaq until Lebron got there). No one cared about the Nets even when they made back to back Finals apps, Kidd re-signed b/c he made more money and the nets were his team rather than trying to hop on the back of Duncan for a title.
Guys go where they think they can win and Cle had the ability to win titles w/ Lebron there.
