Unpopular opinion alert, but for me, the best case scenario from both a Spurs perspective and a London perspective would have been to have Spurs and West Ham groundshare (and likely co-own) at an enormous, say 85k or even more, stadium in Stratford which was created by a pre-purposed digging out of the running track a la what was done with the City of Manchester Stadium, as the centerpiece of a national sports complex, including a stadium development of the warm-up athletics track as the "athletics legacy" of the games.
A stadium where the club's matchday revenue would be tied to ambition in attracting the maximum number of supporters to attend matches rather than how many bells and whistles the club could dazzle plutocrats with.
Best of all would be doing that at a Spurs-only venue in Tottenham, somewhere where the public transportation links could make that feasible, but that was never possible. It was possible as part of the Olympics development, and the shambles for spammers and London taxpayers could have been avoided, with Spurs benefitting in a way more material than just schadenfreude.
