^ Yep , the old adage was the first bloke picked was the THP , the second bloke picked was your reserve THP.
Tight five identification and development has to happen earlier, this definitely needs attention and supervision over and above age group coaches in the U12-U15 age groups. If the coach has no idea , how are the kids meant to.
All clubs and schools should have a scrum/ set piece coach available that can over look these age groups , rather than trying to turn larger than average back rowers into THP's at 16 years of age.
