I could also see the first as a 10-10 and splitting the other two. A half-point could have been all the difference. If you think about it like this,
Rd 1 - even. The takedowns and big punch negate each other
Rd 2 - close, but Johnson gets the edge, lands a few more, does a bit more damange
Rd 3 - dominant, McCall has the back for most of the round, smashing Johnson while Johnson can do nothing but cover up.
and it gets scored 10-10, 10-9, 9-10 for a draw, how does that make sense? McCall should have won it if you see it that way, he won the third by far more than he lost the second.
We need at least to go to half points.
