1) He found so many idols
2) He actually played the game
3) You can say what you want about how he treated his fellow contestants but that is the thing. He treated people like garbage and still made it to the end
4) He didn't follow people like a sheep.
You might be sitting here reading this and saying "Hey, that sounds like Tony." Well Tony basically played the exact same game as Russell and managed to win which proves that Russell only lost due to 2 bitter juries, a dumb tribe known as Zaptara, and Matt.
Ok before Game Changers started Ozzy had 104 of survivor experience and Boston Rob had 117 days. JT was voted out on day 13
117-104= 13 which means that Ozzy officially beat Boston Rob.
