Tottenham's extremely low quality shots after the Arsenal goal

It's amazing to me that they can even measure a 0.01 XG shot. This comes from James Benge's twitter account.

The XG graph is also interesting. Tottenham has a continuous stream of very low quality shots, resulting in the graph going up in tiny increments. Arsenal has a series of decent chances near minute 17, and then the one high-quality shot resulting in Gabriel's goal.

I'm sure part of it is Arsenal defending in a low block after scoring. But, it also smacks of desperation on Tottenham's part. If you're taking a shot that has a 1% chance of going in, rather than passing and waiting for a better opportunity, you don't believe that you're going to get a better opportunity.
