Blocking the plate

[archangel]

I think I understand the ruling on OBS, and this OP is a HTBT. But this sich could've also gone this way: F2 legally blocking plate w/ball...slide into F2 knocks ball out of glove, F2 reaching for ball (arms length away), runner scrambling for home around F2. If F2 is still standing, then maybe the complete plate is not blocked, if kneeling- possible same,... if laying down due to collision?-then not too sure, wait to see additional action 1st--- still...HTBT.
If not, then anytime the catcher would lose the ball due to contact, it would be OBS?--again not comfortable w/ an absolute......
