El Toro was not completely retracked last year. They did the bare minimum to get the state to clear it.
The "pothole" is NOT near the end of the ride, it is at the first turnaround after the initial drops. Allegedly this is where the coaster actually derailed last year, then the train dragged through the rest of the course before stopping near the brake run. That incident could have been so much worse, but they were lucky.
Also allegedly, GA recently laid off a bunch of their existing maintenance team, so that's an extra bad look. The park's maintenance has been horrific for years, and it's only going to get worse with all the cuts.
The odds of Six Flags putting the money into the ride to fix it correctly (and keep it up) are slim to none. If it reopens, I'd bet another incident will happen, and that will be the end. The coaster has felt unsafe for years (to those of us who remember how it was when it opened), and now it's actually unsafe.
And Toro is the only one that gets attention, but that's far from the only questionable coaster there. It's a mess.
