8 Man Football

Hallo fellow coaches,
I am an american football coach in Italy, with Mantova Mustangs at the moment.

Maybe you know that football in my country is played in spring with all the teams, organized in the form of clubs, and governed by Fidaf, the National Federation, the governing body of our sport in the Country.
Football with Fidaf is played in three divisions:
Div 1 and Div 2: that play 11 man by NCAA / IFAF (international federation of american football) rules and regulations;
Div 3: that play 9 man, with the above modified rules.

I am also in charge of a separate amateur organization, IAAFL (international amateur american football league, which is part of AICS, a sport promotion body in Italy and the world).
We have been authorized by Fidaf, through a special agreement, to play 8 man football in 2018, from march to june, with our small amateur teams.

I am planning to adopt the NFHS regulation with the due modifications foreseen for 8 man football.

I would highly appreciate any advice, suggestions and useful information and/or resources for the best application of regulations and officiating procedures / mechanics.

Thanks in advance for your help.
I am looking forward your replies
