Drew Sutton types are readily available in more than half the systems in baseball at any given moment and some teams have more than one.
Point being, it isn't a given. Nor is it a given, for example, that you'll have a lefty out of the pen ready to come up. These guys are nice to have in a system, providing ready depth, so that the organization doesn't have to go begging. That's why in plenty of cases I value minor leaguers with those skillsets (whether it's LOOGY or speed + defense + positional flexibility) over kids who are pure projection with no professional track record of note. At some point, the prospect hype fades and you have to take a more practical look at these players, IMHO.
So, right now at least, just to cite a single example, I would have Sappelt higher than Juan Duran. Doesn't mean Duran can't shoot up the list, but he's going to have to break out first. And on and on....
