#3 A lighter schedule means Finn sticks around longer
While NXT now has a live primetime TV slot on a major cable network, there are still a few things about it that make it appear, well, like a "lesser" brand. Don't get me wrong: these are all things that will be worked out in time and don't actually make NXT inferior - it's just a perception thing.
One of those elements is the fact that the show is filmed weekly at Full Sail University. That's no knock on Full Sail. I've been to the campus, it's a great school and an awesome place to watch a wrestling match. But, it's clearly a smaller arena than where RAW and SmackDown take place. One of the benefits of that, though, is that the NXT talent clearly have a lighter travel and work schedule than those on the Red and Blue shows.
Finn Balor is 38 years old. That's not elderly by any means (I'd be one to talk), but also consider both his injury history, ring style, and personal circumstances. He's spent a significant amount of time on the shelf during his WWE career, and while the way he works is exceptionally entertaining, it's also highly risky.
And, then take into account that he's a newlywed, as well. Now, his new bride, Veronica Rodriguez of Fox Sports, obviously knows the kind of life a professional athlete goes through, but it has to be pretty enticing to be able to start, at least, the first few years of a marriage (and maybe a family?) being able to be a pro wrestler and put down roots - even if they are in Florida (I'm kidding, Florida. I love ya.)
Most, most importantly, this will give Finn the lighter schedule to reduce the wear and tear on his body, which hopefully means that we'll still see more Finn Balor on our TVs for a long time.
And, also on that note...
