2 too many passes.. he would have needed a third td or to be 16/16 with two...The booth announcers were questioning why it wasn’t. They asked how much more you have to do to be perfect. He had a great game,and they weren’t little dump off passes.
Td/attempts is part of it... and I guess tge magic number the math wizards back in the day came up with was 1 pass td per 8 attempts... I think it was all geared around typical drives starting on the 20 and typical passes being 10 yards when it was concocted...
