Before you blast me hear me out. I don't think this is so cut and dry. As of now, best case scenario is that Mac would be the 5th QB taken and would probably not be in the top 15. If he stayed one more year, he competes next year with Sam Howell, Spencer Rattler, Bo Nix, Kedon Slovis and maybe the dude from Georgia. On this list, Mac is the 3rd QB taken. In this years draft Joe Burrow received total contract of $36 million as the 1st pick. The top 5 picks were all above $30 million for total contracts. Once you get past pick 15 in last years draft the total contract money drops below $15 million (A.J. Terrell got $14.3 million as pick 16). So, hypothetically, if Mac was pick 20 this year, he would get around $13 million. If he came out next year and made it into the top 10, he would get somewhere around $20 million. If he were higher than that, the numbers get up near $25-$30 million. Seems like quite a bit of money he would potentially lose by coming out this year.
