I may be wrong but I believe I've only seen it happen to my guys who had single digit pitches. I've hoped it would happen to a few guys who had ~20 ratings but they unfortunately keep the pitch.
Example:
Ed Green dropped a 7 rating on his P5 in his 2nd pro season. Whereas
Josias Cordero had an 18 on his P5 in his second pro season but kept his.
Edit: Just realized you can't see past ratings. Gonna have to take my word.
