=================================================
Above is what will appear in the front of the Rules book this coming season. (I had it in the nice little chart form, but the forum keeps rejecting the post for being over the 10000 character limit, so I've cut it down to just the text.) I'm posting this as it sheds even more light on the coming rule changes. Particularly notice those editorial revisions. The first one is big change for me. The previous wording said excessive blood on the uniform so I used to allow kids to play with some blood on a jersey. That will no longer be the case.

And no, Tony, a "timer's mistake" isn't defined. But you are certainly astute to ask for a definition of this term as well as "obvious timing mistake."
