Angel Rivera gets to officiate big matches, and the Big10 announcers generally say he is a good ref.
That said, I do not like it when he is officiating. It seems like there is always some controvery with his calls, and I think he injects himself too much into the matches. There seem to always be issues with restarts.
This is my personal opinion, which may are may not be correct.
I wonder what others think.
