The problem with Sam (and the rest of the so called 'Burgi') is that they have been hyped to the max ever since they have gone to Australia and yet they havent really turned out to be these supreme world beating athletes that Russell crowe and the rest of 'Souffs' made them out to be.
Sam... decent enough player on his day... has missed far too many games through suspension and injury. Not even the best forward at Souths let alone the NRL. Touted as the darling of channel 9 although his popularity is waning as a large proportion of footy fans now see him as a 'grub' because of his antics on the field. Just been dumped by his girlfriend as well so might fancy a fresh start back home.
George. like Sam a decent enough player but is also known for his embarrassing off the field incidents (smashing a car window in Cairns and taking naked selfies) although most people admit he is just as good a player as Sam (some would say better - much to the chagrin of poor Sammy boy - despite the fact it was his late high shot on SBW that cost his side a place in the final against us

)
Tom. An NSW cup player - nothing special.
Luke. Pretty hopeless and not even good enough to make the England RLWC side. However he's not that bothered as the 'lifestyle' in Sydney is all he really wanted.
If Sam does move back to old blighty and play union he is unlikely to make the grade. He is no Sonny Bill .. and to the best of my knowledge hasnt played the game. He has no chance of making the England world cup side - certainly not this time around anyway.
If he does go at least we will all be spared the hype and programmes that show the 'Burgi' eating their lunch, hanging out on the beach and tying their own shoelaces.
Personally though I cant see him leaving the NRL.
