@Cooposo - I don’t doubt what you say and you appear to have been an Above Average Athlete yourself. Considering the strength, endurance, & toughness required to be a TOP Rugby player —- why don’t most of these guys tryout for the NFL, play a more “glamorous” Pro Sport, get paid the Big $$, and get mobbed by Hot Girls ie: Celebrities, Swimsuit Cover Girls. Name the “Rugby” version of Tom Brady?
Football is extremely…let’s say…position selective?
Let’s take a defensive tackle in the NFL. They are absolute giants. Huge, strong, heavy. If a defensive tackle in the NFL can control his gap and consistency require the offense to dedicate two blockers to him, he will make millions upon millions. But many of them can’t get up and down the field too well because of those very traits that make them a good defensive tackle. And that’s ok. They have defense ends, linebackers, and defensive backs to do the tackling for them.
That NFL level defensive tackle probably won’t be able to switch to high level rugby very well. He might have to lose 50-75 lbs and give up bulk to be able to get up and down the field.
The inverse is also true. Take a prop in rugby. Usually the strongest, heaviest guy on the field. But he would be useless at a high level of rugby if he can’t also get up and down the field for the entire match, ruck, tackle, scrum, lift, and carry the ball. He’ll even run with the ball and score tries sometimes. He could probably do ok at a few different football positions, but he’s not going to be the prototype for any particular position.
This dynamic exists across the two sports. High level football players are usually freaky athletic specialists, rugby players super tough generalists.
Ive followed a few high level rugby players that try to break into the NFL and it hasn’t gone too well. I know a few freaky athletic guys that were discovered when they were younger and diverted into football from rugby, and they did quite well.
There are also intangibles to take into account. A professional rugby player, say, a winger, wants to make the jump to the nfl as a running back. He has to read blocks, work with an offensive line in front of him, catch rockets from his QB, and block. He didn’t do much of that in rugby, and when everyone around you is a freak athlete, doing those things great makes or breaks NFL players.
