i call bullshit on the black belt/trained fighter bit though. glenn sees the shot coming and sticks his left arm out under dannys incoming right instead of covering or blocking.
Maybe, maybe not. Belts don't mean much in the real world. I've known black belts who have never been in a real fight, for whatever reason. There's different dynamics to really throwing down. When my ex got her TKD green belt (I think), she told me should was pretty sure she could take me. I asked if she'd ever been in a fight or been punched in the nose. Of course not. I said maybe we should revisit when she'd been punched in the nose, because there's really nothing like the jolt of a pop in the snookum.
Like you said, Glenn drops his hands. Rookie mistake or the mistake of a guy used to using his size to intimidate.
