A few things I can remember from the old Quakers site.
Graves absolutely said they could stay but the framework of the contract was so outlandish it made it completely impossible for the club to continue to exist after the first season if they did.
Ice prices would go up exponentially, the first payment to secure ice was so high there was no way possible for the club to collect the money quick enough to pay for it. It was due by June or something. All Quakers uniform purchases would go through the Ice Line pro shop, Graves would take a % of the profit which I think was 10%, but probably more? There's more, I just can't remember off hand.
Long story short, he didn't offer the Quakers an option to flourish, it was framed exclusively for failure. To force them into caving to his demands or leave.
They left.
