I think now is a great time to change the 5 match a day rule, but not make it unlimited. The only way to change the 5 match a day rule is to propose it like this:

Wrestlers will be allowed to participate in 6 matches in a day, if they are participating in a tournament with a 16 man bracket.

This is a financial issue now. There are many two day tournaments that could be wrestled in one day if this rule is changed. This would help schools defray costs of travel and lodging and would allow many schools who have recently been forced by their districts to drop two-day tournaments to get back in the tournaments they want to be at. There is no need to wrestle 8 times a day in a dual tournament or a tourny that uses pools. The season is plenty lengthy to get enough mat time in.
