You're way overstating the importance of Griffin to the franchise. His career in LA was marred by injuries and postseason disappointments. We're still talking about a team that has never made it past the second round of the playoffs. And you can't have Lob City without the Lob, so it was actually Paul who was the catalyst. Anyway, the Clips weren't going to make it any further with that group. The front office knew it, the coaches knew it, the players knew it, and even the fans knew it. Everyone was ready to move on. Trading Griffin will have a greater impact on the team's history and success than anything he accomplished while he was there.
People are taking the organization seriously now due to the change in ownership. Putting Frank in charge of operations, letting Rivers stick to coaching, and bringing West in as a consultant...these are the reasons why the perception of the team has changed. The Paul and Griffin trades kicked off a domino effect that has the franchise in the position it's in now.
Until the Lakers put a roster together and start winning games and titles again, they'll be stuck in the past. And until a free agent comes forward and says, "I refuse to play for the Clippers because of what they did to Griffin," then you're just telling stories.
