Three pages, most of which can’t even agree on what happened despite the benefit of super slo-mo, yet people seem convinced that Jack knew.
Given the rarity of this scenario, and the full speed reality I’d been very surprised if Jack knew exactly what had happened and therefore there is no reason for him to concede the point.
I tend to give players, and people in general the benefit of the doubt. I also know that I haven’t played that much tennis, and I tend to be unsure about many things, so I’m positive that in a similar situation, I would not know exactly what happened.
That said, the slow Mo should make it obvious to everyone what happened.
The only way a ball could be shanked straight up like that legally, is if it hit the top corner of the bottom frame. In that case, it would not hit the ground at all. If a ball hit the ground and then hits the frame there is no way for it to shank straight up like that.
The replay and the GIFs clearly showed the ball hit the ground. This only leaves the possibility of the ball hitting the frame, then hitting the ground, then bouncing straight up and hitting the racket again.
Even if you can’t clearly see, that’s what happened, it’s the only physically possible scenario.
So regardless of how you think of drapers behavior, or what should be the outcome: there should not be any doubt as to what actually happened. Just because some people are saying there’s doubt doesn’t mean they’re actually should be.
