If this happened, it'd be like that commercial.
*Knicks* "Take that Memphis; you lost Gasol! You can't have your cake and eat it, too!"
*Spurs come in* "Guys, if we have cake, we should eat it."
*Spurs sign Gasol, are relevant for next 7 years with him, Leonard, Parker et al.*
Then, Gasol and Leonard both get hurt 5 years in, the Spurs magically get the #1 pick, draft Dikembe Olajuwon and are relevant for next 20 years.
