Some rather uninformed comment on this thread, which is fair enough since this is a rugby forum.
Adongo is projected to play linebacker, a defensive position, and will most likely ended up as a pass-rusher, given his frame and strength. That means his job will largely be to fight through the offensive line and hit the QB.
For now, he's playing special teams, which is often the way NFL teams transition raw players into a bigger role. He played a dozen snaps on Sunday, which means he was on the field for 12 plays -- all of them special teams plays, meaning punts, kick-offs, etc. His job is to clear the way (block) for the guy on his team who does receive the ball OR to tackle the guy on the other team who receives the ball. The latter requires him to fight through - "throw off" - the other sides blockers. Proving that he can do that consistently, accurately, and forcefully will be key to how quickly he gets a chance on the defensive team itself.
The kick recovery bit that people are talking about is largely irrelevant. It's not his job to receive the ball. I didn't see the play in question, but probably it was a wayward punt that he was forced to make a play on. It's great that he didn't screw it up, but not what the coaches will care about.
As for a Hooper-like involvement? No.
