Galvin should have negotiated a deal.
$210,000 is $680,000 in today's money. That is an incredible sum given it was a starting offer. The check was cut and ready to go!
If Galvin could have got them to agree to $300,000 that is like $800K today and you have to take that there is no choice. Risk free with no need to go to court? Galvin's financial problems are solved and now he has money to advertise his practice.
Of course that means no story, no movie and no big emotional ending.
In reality there is no way they would have offered that much back then. $50,000 maybe.
