Great wrestling matches come in all shapes and sizes, of which proof was found earlier this year when Goldberg and Brock Lesnar brought the house down at WrestleMania 33 despite going fewer than five minutes.
But at the same time, it's rare that a bout is afforded "classic" status without going, at minimum, 25 minutes to half an hour. This is because, in most cases, there's bound to be more (and better sold) spots, scope for long, drawn-out story-telling and, best of all, a dramatic, nail-biting climax.
If you go for more than 45 minutes - as precious few competitors in wrestling history have been allowed - finding the right balance between gripping, long-game action and a resthold-heavy bore-fest is extremely difficult (hence so few are ever entrusted with that task).
When it works, though - and this is something anyone who watched this year's Okada-Omega NJPW trilogy will be able to tell you - it really works, and some of wrestling's 45-minute+ matches are rightly regarded as being among the very best in the industry's history.
