I beg to differ. For me, you really-really bottle it when you're handed an advantage by your opponent, but you don't have what it takes to get over the line.
Bayern Munich had been offering the title to BvB on a plate for several weeks, and Dortmund were like: "Nah, you can have the bowl. We don't care much about silverware here".
The Heat needed a three-points masterclass to beat a sorry Bulls team just to make it to the playoffs. That was their starting point. Similarly, if Arsenal had lost the title to an 80-points City team, i'd call it a proper bottle job.
