Why is tom brady overall lower than carr and dak

There are a couple of Tom Brady cards that are higher rated. It basically boils down to this...the harder it is to aquire everything in a set the higher the rating on the reward at the end. But with all the sets in the game there seems to be half a dozen variations of any single NFL superstar in this game. I can't see the sense in a couple sets other than doing it out of boredom after completing everything else...like giving up five elites rated 89 for 1 rated 92? That is a definite pass on that for me, lol.
