Catchers are so flipping weird.
Kirk a sad example (though his book isn't written yet!).
But Jansen is a great example. 16th round pick and looked like a nobody his first 4 years in pro ball. Suddenly he explodes in his 5th year and he's a hot name to know as a bat first catching prospect with major concerns about his defense. Gets the call and he's actually a defensive whiz that can't hit. After 3 or 4 years he's settled in as a solid all round C, both bat and defense. Weird career arc.
