Nope. You pay them b/c of individual results to a degree, but more than that, you pay because of the results they enable for players around them and how they dictate what the opponent does.
You pay your QB b/c he improves WR/RB results.
You pay your LT b/c he improves QB results.
You pay your DT, b/c he improves LB results.
You pay your DE b/c he forces the offense to shift blocking.
You pay your RB b/c he forces the defense to commit an extra safety to the box.
The list goes on and on, and varies from team to team. But no big-money position is paid in a vacuum. When you pay DLaw, you're also paying for the production of Quinn and Collins. When you pay Zeke, you're also paying for Gallup's production against man coverage. The positions generally paid in a vacuum- LB, SS, FB, TE - generally make the least, because they have the least amount of influence on the players around them, or are a product of the big-money players.
Do you really think that Jordan Phillips should get a larger contract than Aaron Donald, or that Benson Mayowa should make double Jadeveon Clowney? No.
