Help me out because I am not clear. Is "the tackle box" the hash marks? Do the refs make an imaginary "tackle box" in their mind?I think Mike Reed covered it.
To help you out, Roach, the UIL makes rules designed for 11-man football that get passed down to 6-man. Even though I still do not like it, this rule makes more sense in 11-man.
A retired 6-man coach should get involved with officials and start interpreting the rules for 6-man. For instance, if the 11-man rule references "a tackle box," then the rule only applies in tight because there is no tackle box in 6-man spread. While little guys being able to cut block in the backfield in spread is a big deal, the rule is not as big of a deal in tight.
