I'd be very concerned with his health issues. Here's what he said back in 2015.
"I couldn’t pick up my daughters and put them on my shoulders in the swimming pool. I couldn’t play catch with them. They’re runners, and I can’t move to watch them at a cross-country meet.
"What I’ve been through the last eight years has been very challenging. There are things I can’t do as a husband, there are things I can’t do as a father. But they’ve never left my side. They’ve got to take my shoes and socks off after games because I can’t bend over. They’re always right there to help me, through the good and bad."
Maybe he's on medication that has dramatically improved his well-being? Hope so, because if not I can't imagine he can sustain this job for very long. It's unbelievably taxing on the body and mind.
