I don't know that the prospect of wrestling Sanderson is quite as intimidating to wrestlers who haven't grown up in America. In 2004 there were guys good enough (Sajidov, Gatsalov, Romero 2/3 times) to straight-up beat Sanderson as a takedown game. I don't think anyone that good is competing at 84 today, which is why I believe Sanderson has a chance to win despite the long layoff.
Most guys will probably try to keep Sanderson's hand off their heads and try to avoid their ankle picks, and do whatever they do best. Of the top contenders.. Sokhiev will stall like hell, and try to hit that one double leg takedown or pushout. Aldatov will try to rack up points on his ankle lace early and then hang on for dear life. Ganev, the defending world champ, is a brawler but he is smaller than Sanderson and hasn't wrestled well this year- I think Sanderson would beat him pretty convincingly. I don't know much about the Russian champ Saritov.
In the past, Sanderson- like other American wrestlers- would sometimes get in trouble by getting unbalanced in a scramble position and giving up back points. As long as he keeps to clean shots he should be fine, but if he gets caught under guys they will try to chest or crotch throw him Hopefully wrestling mostly folkstyle with his team hasn't re-inforced bad habits.
