Legal of illegal kicking? - What is and what isn´t pass

[Base]

NCAA rules games

1-10 from A-40: QB throws ball, which would be incompleted, but middle linebacker places his foot so, that ball doesn´t hit the ground, but his foot. There is no doubt, that movement of linebacker´s foot was intentional (it wasn´t accidental contact of ball and foot), but there was no "kicking movement" - linebacker just positioned his foot so, that ball hit it, he didn´t "swing" his leg.
After this, he or another Team B player catches the ball, which never hit the ground and runs into Team A´s endzone.
Legal (Team B´s touchdown) or Illegal (1-10 from B-45)?


1-10 from A-10: QB drops 5y back and towards the sideline. Linebacker follows him and first contacted him on 5y line and drives QB to 3y, where QB is loose again (contact is maintanted but QB is clearly able to run by himself. He isn´t driven or pushed back) and runs into endzone, where (from -1y) he throws the ball forward (towards opponent´s endzone), while running so, that he faces his own endline and the movement of arm is not above the shoulder (nor Jake Plummer style) - he just wants to escape from sack a throws the ball away. Ball hits the ground on 5y where is recovered by another Team B player (who is still on his feet) and he returns the ball into Team A´s endzone. Is it
a) sack (and referee didn´t blow the whistle, where forward progress has finished)
b) safety (because of intentinonal grounding from the EZ)
c) touchdown (because throwing the ball in such way is not passing, but fumble)
d) anything else?

In case a) should be ruled, consider the situation again without the contact between QB and LB and just rule the forward pass/fumble

In the first one, if he intended to use his foot the play the ball, it's kicking. It's not like the ball just hit his foot by accident, which would be legal. Of course, like so many other plays, one would have to see it to judge it.

I'm a bit confused by the second play - looks to me like intentional grounding in the endzone and a safety. There's nothing in the rule about "how" the ball has to be thrown. If the release of the ball is intentional and it goes forward, it's a pass. Like one I had with a punt blocked back to the punter. He caught the ball, panicked, and just flipped the ball away and it went forward (incomplete pass and grounding).

The "recovery" by B doesn't matter since the ball became dead when it hit the ground.

OK, have the same opinion, just wanted to be sure. Thanks
