That's not "pretty different views". That's agree on all the basics but having a different sense of how much talent matters.

"Malcolm Gladwell's point-of-view about deliberate practice is different from Ericsson's view."

"Hard Practice" vs "Soft Practice" is the center of the argument, it is the point of contention. No one is going to argue that practice isn't important, they are going to argue how you should practice and how much it matters compared to other factors. They disagree on both of these points, so no, they don't agree.

If you focus on the difference, yes, it is the major difference between them. But if you focus on the main point (the overwhelming importance of 10 year of deliberate practice for one to become a top expert in a field), it is non-essential. There is no concrete empirical answer to how much exactly talent matters, even now.
