It is a £1m gamble by the Rugby Football Union and Saracens - it is a chance in a lifetime for Andy Farrell.
After the service he has given to rugby league, few can begrudge Farrell the chance to test himself in another arena.
After all there is little else to achieve in the 13-man game for the
Challenge Cup-winning, Championship trophy-lifting, Great Britain-captaining, Man of Steel-receiving, OBE-accepting Andy Farrell.
In rugby union, he will get the chance to disprove the strongest held theory in both codes: that you can't be an outstanding forward in the two games.
Backs have it easier in crossing the divide, the big men up front
must learn altogether different skills.
But if any man has the mental strength and the ability to turn from being match-winning packman in rugby league to an inspirational leader in union, then it is Farrell.
The big question is why is the RFU taking such a gamble.
The estimate is that it will have spent more than £1m on the player by the time of the next rugby union World Cup.
Robinson is the captain of England's rugby union side
He has a potentially dodgy knee, he will be 32, and he has not yet played a serious game of union.
The claim has been that Farrell's departure from league will be
massively damaging, but it will not be.
Wigan may well sign Sonny Bill Williams as his replacement, an exciting swap.
Britain will promote another young forward into their squad, and Farrell, though not forgotten, will become part of the game's history.
The fact that they want him so badly does reflect badly on union.
The £1m gamble casts doubt on their own abilities to nurture talent from within the code.
By the time of the next World Cup, England's most exciting back could still be Jason Robinson - and their most influential forward, Andy Farrell.
Now what does that tell you about which is the stronger code?
