It suffices to say he is an expert, renowned, and respected on The Game.
In his blog George Cumming's Football Blog, he writes about a variety of topics about The Laws, various incidents, and soccer pop culture in general. His writings are very good, and his site is also linked to the right, as I have noted before.
Recently with all the discussion of GLT and FIFA stating they will adopt it, he came out with a couple of posts that I thought were really insightful, and one that was way out of the box thinking, that was really, really clever.
His first, Goal line technology for .01% of world football, I think is a simple, yet eloquent recitation of the reality of FIFA's decision is on GLT.
Both are good reads to put GLT into perspective that we will start to see soon around the globe.
