Could be that he's found some inner peace, but it could also be that he was just distracted with other priorities. Gilman said in an interview (before the finals) that he wasn't even sure if he was going to compete in this cycle's Olympic trials, and mentioned struggling with some domestic adversity over the past several months. Not making excuses for him, but sometimes life happens, esp at that age. He's also not the type of person to randomly bring up stuff like that, so it must've been pretty serious. Whatever it was, I hope he & his family are okay.
