Yeah, if the starter isn't lining up at the correct angle it will cause problems. But you might want to check the ring gear(if a 6 speed) or the flexplate(if automatic) to see if there are damaged teeth. If the teeth are damaged it could keep taking out starters. I had to get the ring gear replaced on one of my old SS396 Camaros. The engine usually stops in the same general area of rotation when you shut it off. So when you go to start it the same teeth on the ring gear or flexplate take the abuse. Once they get damage a little it only gets worse.
