#1 Use More Indy Wrestlers
With the exception of Patrick, last season of Tough Enough didn't feature anyone with previous wrestling experience. This put WWE in a corner when it came to how the winners would be used.
By intentionally picking rookies, management made it so we wouldn't see the winners for a long time, if at all. What's the point in giving someone a $250,000 contract if they might never make it on television?
It might be more interesting to watch people who have never stepped into a ring before learning the basics, but after six seasons of the show without a winner who went on to be successful, it's time to start thinking about making changes.
Picking indy talents for the show doesn't mean there is nothing for them to learn. Many would be coming in with no previous TV experience, so they would have to be taught how to present their character to a larger audience.
Also, indy wrestlers with only a few years under their belt would still have plenty to learn between the ropes. If anything, wrestling fans would like watching people who are already passionate about the business instead of people who are just looking to get famous on a reality show.
