We're working in a vacuum here, and we're just fine with that. We know that players like Tim Duncan and Dwyane Wade are just about the best thing the NBA has to offer, but should their performances over the season's first 10 days leave them ranked among the league's top 20 players? Why should we pretend to know better, when it's so fun to throw a bit of exposure toward the players who have playing out of their minds? So, until orthodoxy rears its boring head, we present the second installment of the NBA Player Power Rankings (all stats through Thursday's games).

Would you explain the boldtext?

Thank you

BW, the idiom is raise/rear its (ugly) head, which, courtesy of http://idioms.thefreedictionary.com/rears , is explained as:

if something unpleasant raises its ugly head, it becomes a problem that people have to deal with

So, orthodoxy (the conventional) will eventually take over, and will have to be addressed.
