Being able to plug an inferior WR into Wes Welker's spot doesn't make the gameplan foolproof because the defense will then not respect that WR and will adjust accordingly. It is how you exploit match ups. This isn't a video game where you only have so many set plays and players. When Gronk goes out and Woodhead goes out, you don't run the same packages because Vareen does things better than Woodhead and vice versa. The defense can't sit on Hernandez when Gronk is on the other side. Plugging different guys in makes it an easy system to be in but doesn't mean the game plan is the same. Defenses adjust and you have to adjust too.
It is like Chess. Just running the same plays with lesser guys won't work when the defense adjusts. It is the same as a defenses top DB going down. You can't say "its the 3-4 and the backup can just be plugged in to cover WRs." Offenses know this and attack the lesser DB. The counter to that is safety help which opens up other things for the offense. It is adjusting on the fly.
The Article talks about concept.
It's like you you design a shelf, now you can either use a flat head or a Phillips screw to secure the shelf.
On game day, you don't need to go find a particular screw to use.
Now the flat head may not be as strong for a certain place, but you don't need to go redesigning a new shelf and spending time to build it.
