I'm aware of the situation, and baseball is littered with teams that blew a lead in the final month. Nothing about the Nationals situation is bulletproof. Part of enjoying it is not being a blind homer unable to recognize reality.
What reality? That they have the largest division lead in all of baseball?
It's actually rare to blow a lead this large this late in the season. Why automatically go to the lowest common denominator? Unlike the Braves which are SIX games back, the Nats are in FIRST PLACE.
Could they lose the lead? Of course. But that hasn't happened. That isn't close to happening. Why invent scenarios that don't exist?
Seriously, what reality are you talking about exactly?
