Wales accept they were outmuscled against Ireland and forwards coach Jonathan Humphreys has explained what they're doing to fix it.
Red jerseys were almost constantly in retreat during the 29-7 defeat at the Aviva Stadium as Irish ball-carriers crashed over the gain line time and again.
It meant Andy Farrell's side enjoyed plenty of quick ball - 71% of their rucks were under three seconds - meaning Johnny Sexton and co were able to attack an unorganised defence.
