Thanks for the attention. Those answers didn't exactly answer my question, so I'll rephrase it:
If I put an aging ballplayer into AAA to avoid needing to give him game time during ST, plus avoid the alternative of him getting a ratings hit specifically accrued by inactivity during ST while a player is on the ST roster, does he still get an extra inactivity hit, per se? I mean that, regardless of what descent in ratings will occur anyway.
I'm guessing the answer is "no." (And Mike, your data does help me make that guess, thanks.)
