What sort of shape is he in? How quickly can he get back to his best? If he can do it quickly then why not? I would prefer Sandow to Eastmond or Roberts.
Yes he left on bad terms and there is baggage but there are other threads on this message board about how rugby league is going down hill, boring, quality in decline. In the last few years the time that was most exciting watching Wire was when Sandow was here. RL is supposed to be an entertainment product and he makes the game exciting.
Most important thing for me is, is Sandow fit enough to do himself justice. There will be a lot of people from other clubs and also at Wire, who would view his return cynically, and say it was a waste of money. If he was unfit and not able to produce his former level he would be treated as a figure of fun in the English game and get laughed at. If he was fit, then he would be a cut above the rest of halfbacks in SL, could be the player who could win us trophies, nobody would be laughing, and he would round off what had been an up and down career, as being a real winner.
Lets hope there is some potential in this story.
