This is the albatross around the neck of the franchise i said it would be when they made this ridiculous deal. The trade was questionable as Perk was always a poor fit, but the contract was flat out horrendous, especially considering Bostons last official offer was 4years for 22million (though rumors were of 4yrs for 30million).
OKC has two options= 1) Let Harden walk. Keep Serge, and replace Harden with low cost offensive minded players (Jeff Green can get a minimum deal to come back if his health allows). 2) Amnesty Perk and hope James and Ibaka will take deals similar to the one they gave Perk.
You did say it I remember and you have turn out to be right.
As for your options that seems to be the case. Problem is this if they amnesty Perkins there is no guaranteed that one let alone both will take reduce deals. They could end up losing all three taking that route. I think the first option might be the realistic option. Problem will be is Harden just won sixth man of the year and is killing it in the playoffs. His value and popularity is through the roof. Will OKC be able to make the hard decision and let him go?
When Magic retired due to his announcement, the exact same thing was said. Nobody gave a shit about the Sedale Threatt Lakers. That didn't stop them a few years later when they signed the top free agent, Shaq, and flipped Vladi Divac for a high school kid name Kobe (again great fucking GM). Think aboout this scenario with a Kobe retirement (lets say at the end of his 3 year extension)...in 3 years when Kobe's contract end, Kevin Love will be a free agent (since the Timberwolves refuse to franchise him). Now which sounds more attractive?...playing in the town he went to college in and for a franchise with a storied history or the fucking Timberwolves? Love/Bynum would put the team right back to contenders.
