You can't delay graduation. It IS a match violation and you will not be able to use the NRMP to find another program. Reading your post history, it seems you didn't match. You SOAPed into a specialty you didn't want. This is one of the major cons of the match that's been preached about and written about for years -- desperate students take whatever offer because they're concerned about not being employed at all.
Unfortunately, once you accept the offer, you're bound by the Match agreement and that's that you show up on day one. That said, you're in a predicament that sucks, but isn't hopeless. Do you mind telling you which specialty you SOAPed into?
You can re-apply to the Match during intern year. Depending on how rigorous the specialty you SOAPed into is compared to the specialty you want, you can actually do okay as a re-applicant with intern year under your belt, assuming you do really well this year.
My advice would be to show up for intern year and make a commitment to being Intern of the Year. Don't give any hint of not wanting to be there. Don't make enemies. Work your ass off like you've never worked before. Those who take notice will help you get the specialty you want if you're good at your job. If your hospital has the specialty you want, residents in that specialty may also notice how good you are and when you re-apply, resident input will be crucial.
Put on your big big/girl pants and just go to work. Lots of people don’t like their jobs their entire lived, you can do it for a few years
Your right ... he has the right to be disappointed but at this point especially Bc he soaped he should be glad he has a job and start preparing for it
Seriously, as someone who matched WAY down on my list, the things I thought I'd hate about my program, I turned out to love in hindsight. I look back and it's almost comical that I ranked certain programs above the one I was at.
Here's the logistical thing - Medical schools have to attest during the match process that individuals are on track to graduate prior to the start of the matched position. So, it would be VERY had to justifiably not graduate an individual. Even if the individual failed a required rotation that was occurring in between, there is always May & June to remediate. It is not in the interest of the Medical Schools to delay graduation for anyone with a GME position waiting for them.
