The headline is ridiculously inaccurate. The article, on the other hand, may be accurate but it begs for more information.

What amount of the Leaf's annual revenue actually goes to Phoenix? 

If you take that amount and divide it by the number of leaf tickets sold in a year, you will get the amount that the  Coyote's money issue affects Leafs ticket prices.

I don't know the number but it is small.
