Other interesting things to mention. According to Gareth Thomas ( Welsh RU Captain & most capped player in Welsh RU histrory).
"
For me, league is more physical without a shadow of a doubt. Particularly in my position because where I played in union (centre, wing or fullback) you make maybe six or seven carries a game whereas in league you’re doing 15 to 20, the contact is more frequent and what I found in league is that even on the wing you can never rest.
“In union there’s a lot of kicking and set plays going on which seems to take ages to play, whereas in league if you shut down for a few seconds the players are so talented in recognising that you’re up or you’re out of the line and they put the ball into the air into a gap and score.
It’s 80 minutes of working whereas in union you can rest and have a look at what’s going on in the crowd a lot of the time"
