I'm not a "Troller" (nothing wrong with trolling
) and don't typically fish down your way but the last time I checked, fish can swim. They are always on the move either for some lovin in the spring, food in the summer and fall and warmer water in the winter, in general terms.
I realize if you were to give the Lat / Lon of what you caught there would be fisherman (not anglers) making a bee line for the spot on their next trip.
Having said that, how long do you think fish stay in one spot in order for it to be "Burned".
For me, the answer is, water quality and temp, food and structure.
If something changes or makes the fish uncomfortable, they will leave.
And as we all (should) know, that can change by the hour.
To me there is more satisfaction, and it is harder to find the fish, then it is to catch the fish.
But what do I know, I don't troll.
