Rule on Receivers Re-established after going out of bounds:
NCAA: The only 2 restrictions about players going out of bounds and returning are:
1) A kicking team player may not voluntarily go out of bounds and return. 5yd penalty from previous spot.
2) An eligible offensive receiver may not voluntarily go out of bounds and return and be the first to touch a legal forward pass. Loss of down at the previous spot.
The issue was did our defensive player participate in the opposing offensive player going out of bounds, or rather did our guy push theirs out? From the replays I saw, the answer is no. Then the question is, did another player touch the ball after the offensive player re-established himself but before that player in question caught the ball on the field? Again, per the replay that answer is no. As such, in common layman's terms, "we got screwed!"
