Hey, good for the wrestler.
There are no rights or wrongs in terms of preparation. Each wrestler has a different approach.
Suriano is on one extreme. He gets himself in a zone, and pretty much isolates everyone else that is around him. He was 159-0 in high school, so that approach has worked for him. I mentioned in another thread that I spoke briefly with him between the semis and the finals. While he was seated in the same section as other PSU wrestlers, he was off by himself, and totally focused on his upcoming match. After our very brief conversation, I basically apologized for interrupting his mental preparation.
On the other end of the spectrum is Nolf. He was cracking up some of his teammates at the side of the mat before the start of one of the rounds. And that wasn't the only time I saw him joking around while off the mats. I also spoke briefly with Jason in the stands. He was relaxed, and joking with the teammates sitting around him, but when he spoke with me he was very respectful.
Would Suriano's approach work for Nolf? Perhaps, but it doesn't seem as though it would fit his personality. Would Nolf's approach work for Suriano? I seriously doubt it. And yet these approaches, which are quite different, appear to be working very well for each of these guys this season.
As for the wrestler being doted on by his GF -- good for him. He probably felt that was the best thing for him at the time. I doubt that it had much of an impact on the results of his subsequent match, even if he did lose that one.
