The best-ever WNBA champ?

As the WNBA turns 10 this season, ESPN.com needs your help.

We've done the hard work. Now it's your turn to determine the greatest championship team in the league's history. Yes, we know each former champ was special. But which one is the best of the best? Which one stands out above the rest?

To get us started, Nancy Lieberman already has seeded the past champions (talk about a tough job). But when first-round voting begins Friday, will the ESPN analyst's top seed, the 1998 Comets, stand up to your scrutiny, or will one of Houston's other three championship teams secure your vote? Just how far will more recent champions such as the 2003 Shock or 2004 Storm go? Where do the Sparks' back-to-back title teams fit in? Will the 2005 Monarchs make the cut?

Before then, and in an effort to make sure no one gets left out, we've decided to tip off the bracket with a "play-in game" between the eighth and ninth seeds.

So take a look at the breakdown below of the 2004 Seattle Storm championship team and the 2000 Houston Comets squad. Then cast your vote to see which former champ moves on.

Remember, check back Friday to cast your vote on the first-round matchups. Voting for the all-time best WNBA championship team will wrap up before the July 12 All-Star Game.
