#1 An influx of indie stars sooner

Shane McMahon is widely reported to have had an eye on the original ECW before others in power at WWE did, and to have helped usher in the more extreme elements of the Attitude Era. He is also known as an outside thinker who pushed for an international system to develop stars around the world.
Shane wasn’t known as a proponent of the WWE developmental system that took hold in the mid-to-late 2000s, centered on essentially manufacturing Randy Orton clones with a similar look, crafted in the WWE system without indie experience to mess with their aesthetics.

Had Shane stuck around WWE, he may have made his voice heard. Long before Triple H steered NXT into signing top indie talent, Shane may well have pushed similar thinking.
While a lot of top indie talent ultimately made it to WWE anyway in the last few years, we may have seen them in WWE sooner, and WWE may not have missed out on guys like Christopher Daniels, Chris Sabin, and Jay Lethal who still haven’t, and seem increasingly unlikely to cross the divide.
