The 6 nations rugby comes to a close tomorrow.  Ireland fell short this year against a very strong French side.  Rugby as a business has boomed in these nations off the field as well in recent decades and much of that is down to public equity investment.  But with a clampdown on head injuries will the declining physicality of the game damage the income being earned by it off the field? 

Robert Brophy is the former CFO of World Rugby and now with Interpath Ireland which was involved in the review of Manchester United at the end of last year.
