How Sotiropoulos Wins: Sotiropoulos, a native Australian, will have the crowd behind him going into this one. Sotiropoulos is a tough, tough fighter having never been knocked out and knows his way on the ground, having never been submitted and carrying eight wins by submission. His stand-up is getting better and he's one of the top submission fighters in the lightweight division. Taking this fight to the ground will be key for the Australian native and if he can get it there he will ride to an easy victory.
How Siver Wins: Siver is the exact opposite of Sotiropulos. Unlike George, Dennis is one of the better strikers in the lightweight division, utilizing great kicks to beat his opponents. He's got a ground game as his nine submission victories point too, but that's not his strong suit. If he can keep this fight standing, he can strike his way to victory over the home fighter.
Prediction: Sotiropoulos by submission in round two
