I dont know about some first base coaches. What are they watching? I guess they think their job is too look cool in a golf shirt and straw hat, dunno.
Sometimes they are completely brain dead and asleep. They let their runners get back doored, wander off a base, or whatever.
I have accidentally heckled a few coaches who fell asleep and let their runners get picked off or done something similar. And a really nice vocal sell out with eye contact when they let their runner get dumped is always fun too.
