How do you think Israel Folau would do if he switched codes to union?

i think he would be like lote tuqiri. he's a natural athlete (so he would be good) but he wouldn't be a star. he's great under the high ball which is good in union but i think he would look a little lost because the game is a bit more complex. i think he'll find it a shock playing against teams where a lot of the blokes are bigger than him. there are talks of him switching to afl but i can't see that happening. hes never played afl before and in union he'll have the opportunity to play at the global stage. he could even retire in france where teams have 20 million euro salary caps. your views?
