That, IMO, is what is freeing receivers to be wide open, for long, in stride catches & runs. However, since Os are geared for this type of gun slinging, if there's the slightest hitch, then the QB is either holding the ball too long and can get sacked, or he's throwing it regardless, which is why there are interceptions. Hence, the resulting stats for both teams.
Makes for a fun game, and if you can get over the fact that the athletes hate you & America, then it sort of clears the table to be able to just watch analytically without any passion/care about which side 'wins'.
There’s a lot of debate on the difference between a pick and a rub route. Been a few pick penalties this year actually. But if you build your routes right (such that the defender “just happens” to bump into one of your receivers leaving another open) they’re rub routes and perfectly legal. And they’ve been in the game forever, though it does seem teams are getting better at it and doing it a lot more. Probably because 5 wide sets are basically normal now, with that many guys out in pattern it’s almost impossible not to rub.
