the other team fumbles the ball after taking a hard hit that dislodges the ball?
How is it luck that the ball was fumbled into a group of BYU players and one was able to pick it up for a scoop and score? Sounds like good pursuit, not luck.
How were the interceptions luck? Putting pressure on the quarterback and being in the position to make the interception sound more like sound play by the defense than luck.
On the punt return, he got a good bounce, but there is no guarantee that he wouldn’t have scooped it up anyway with a different bounce. And the return itself was a work of art. He broke a couple of tackles, got some good blocks, and outran everyone else. I don’t think any of that is luck.
