Goff is probably looking at one more big contract, of which next season will dictate a lot. If he plays out of his mind like he did in the last 10 games last season, it’s not outrageous to think he could get something like 4 years / $150MM.
Could he bet on himself, go elsewhere, and still get it? Maybe. Carolina would make sense if he did. But the best odds by far of that happening is in Detroit, in year three with Dan Campbell, Ben Johnson, and the offensive weapons here. And if he does it, and then goes elsewhere to get that payday while Detroit goes to a sophomore who backed him up in 23? No skin off Goff’s back.
