The Indiana Hoosiers have been ranked #1 for much of the season, but can they continue their march to Atlanta and the Final Four?

An annual rite of spring, the NCAA basketball tournament, is upon us and it's time to find your favourites, pick your Cinderellas and fill out your brackets.

Starting with the games on Thursday, March 21, there will be 63 games to pick, with scores for correct picks increasing as the tournament progresses.

Whether you know the ins-and-outs of all the teams in the field, are just a casual fan or would prefer to pick by uniform colour or school nicknames, all are welcome to play and, with a wide open field, who's to say which method will ultimately work out the best? Pit your hoops strategy against friends, enemies and casual acquaintances in our own groups as well as taking aim at the Grand Prize.

The winner of the 2013 Men's Tournament Challenge gets a chance at a $10,000 cash prize. Not a bad return for a few weeks of nail-biting finishes and buzzer beaters!

Schools with rich hoops history, like Duke, Louisville, Indiana, Georgetown and Kansas are all expected to be among the higher seeds, but maybe an upstart like Miami or Creighton will march past them. It could be teams with tournament-tested coaches like Florida (Billy Donovan), Syracuse (Jim Boeheim) or Michigan State (Tom Izzo) or maybe it will be another year for unheralded small schools. VCU, anyone?

From this side of the border, maybe you want to look out for the Canadian talent. Gonzaga, led by Canucks Kelly Olynyk and Kevin Pangos, will be a high seed with the best chance for a deep tournament run.

UNLV has top draft prospect Anthony Bennett as well as big man transfer Khem Birch patrolling the front court and Marquette has Junior Cadougan running the point.

Nik Stauskas made an immediate impact as a sharp-shooting freshman at Michigan and, if Kentucky finds a way to get into the tournament at the end of what has been a disappointing season, sophomore forward Kyle Wiltjer plays a significant role for the Wildcats.

Whichever teams you decide to ride to glory, you can catch all the action right up to and including the Final Four on TSN and TSN2.

So, fill out your brackets and keep track. The Madness is about to begin!
