Bullish on Oil?

After wavering about the price of oil in this Euro crisis environment, I read this article about why the recent strength in oil will continue.

Why $100 crude is imminent.

Not sure why a winding down of contango would cause the spot to spike, because as tankers are brought on shore to unload their cargo, the spot market would be flooded causing price weakness. Or perhaps what the author is suggesting is that as the price of oil has risen in the past year, specs have gradually already unloaded their 'contango' positions?

I hate it when I don't fully understand their logic. Buyer beware!
