No one gave the Oklahoma City Thunder much of a chance heading into the Western Conference Finals series against the reigning champions. They now head to Golden State for Game 5 of the series with a 3-1 lead, and I think the Thunder can complete the upset with a win in enemy territory tonight.

Here are my keys to the game:

1. The Thunder's Size - Oklahoma City has dominated the battle of the boards in each game of the series and has dragged down a combined 130 rebounds over the last two games of the series. The Warriors have not been able to keep possession with both Steph Curry and Klay Thompson struggling with their shooting.

2. Road Warriors - The Thunder have lost just two of their seven road games here in the playoffs straight up and won the series-opener 108-102 here at Oracle Arena. The fear factor heading into Golden State is gone and the Thunder are in the zone right now, not intimidated by anything or anyone.

3. X-Factor - Steph Curry was 6-for-20 and missed eight of his 10 attempts from behind the arc in Tuesday's 118-94 defeat. Wether it's a lingering injury or just fatigue, something is not right with the MVP.

Selection: This is a play on Oklahoma City Thunder (10*)
