No, but they are inherently connected. The player is coached on how the team will respond to that play. What their responsibilities are, what their freedoms are. This isn't simply "I've seen this before, so now I have an edge" - the players still work within their scheme and design in how they will react to those things. That's why I say it's not just about athletic ability - the team works as a unit. It's why a certain LB knows to play contain, or if he is free to take that extra step towards trying to make the early tackle, etc. For DBs it can play out in how they know if they are free to jump a route or not (will there be coverage over the top, etc).
Kearske completing that catch was purely one player outplaying others. Butler's defense was even possible because of the scheme, his recognition, his pre-snap adjustment (which the scheme defines his latitudes), and the coaching/prep on where that ball will be and his responsibilities. It wasn't purely two guys fighting for the ball - the whole reason he was able to make the contest on the ball was because alignment to avoid the crossing rub and knew the route so he knew right where to fight for the ball.
Look at the play, he's not even looking at the WR - it's all play recognition, adjustment, and ultimately his bad-*** execution of it. It wouldn't have happened without the player execution -- but without the other elements, he wouldn't have even been there to contest the catch because he would have gotten tied up in the crossing rub. It's not just a player outplaying another... he was in the position to make the play through their work and coaching.
It's not either or - it's you need BOTH. Your conclusion ignores why we see teams
with talent fail. Or why players with talent can still vary so greatly in their output depending on where they are playing. It's not 22 guys competing individually... or even one guy trying to beat 2-3 guys. This is the NFL and the reason the same stuff doesn't work week to week against everyone is because teams scheme and work together.
No, you aren't going to get the great catch if the guy doesn't execute and actually COMPLETE the catch - but the reason the guy is able to get open in the first place is heavily dependent on the coaching and scheme... or the inverse, why all-world Megatron or similar can't get open against an inferior athlete.
Or why the Patriots who threw the ball over 50 times were
still able to keep throwing the ball. It wasn't just because Brady is a greater athlete than the guy trying to defend the catch... or that Amendola is the best athlete on the field... it's scheming to create those opportunities which the players must execute within to capitalize on.
Butler is in the position to make that catch because of the work they put in the two weeks prior. If Butler was playing one on one sandlot football he wouldn't have even been in the neighborhood to make the catch as he would have been 3 steps behind due to the block intended to free up Lockette.
But Butler is playing 3 yards off the line of scrimmage. It's a two step drop throw... before Russell even throws the ball Butler is already B-lining to the point of the catch and gets there at the same time as Lockette. He recognizes the play as soon as Lockette turns parallel to the line of scrimmage and is hauling to get to the point to contest the catch.

#83 has just turned on his slant and Butler is already taking off for the point of the catch. Russell hasn't even begun to throw, he's just taken his two steps and turns towards his receiver. At this point everything is already pre-determined except for who will make the catch. Russell knows exactly where he is going to throw it, and so does Butler. Butler is committed to trying to make the INT and never defends the WR at all. He's playing ball all the way because he knows the throw and where it's going. Butler makes an impressive closure on the ball and makes the great play to make the catch and hold on through the contact. But the whole reason he's there in the first place is... he had to know the play. And that comes from their prep and coaching. It's not because Butler is some diamond in the rough DB the world just didn't know about made some superhero move. He's the nickle/dime DB who through coaching had an edge and performed to brilliance in those two seconds.
