Here is the problem with football's return. To make golf work, the PGA Tour are hopeful of securing a million tests for Covid-19.

Without a crowd, a three-ball group amounts to six people down the fairway, plus a scattered broadcast unit.

Even so, one million tests. Football, though, is a contact sport.
