How to fill out a winning bracket

SULLIVAN, Ind. (WTHI) - The tournament college basketball fans look forward to year-after-year is finally here!
     
It's downright madness; March Madness that is. There are 67 games in three weeks. However, with each game comes a big decision.

Every game has a winner, but how do you know which team to choose?

"I take the professionals picks, I take my own picks, I take upset picks," said Kevin Arnett. "I throw them all together."
     
Kevin fills out 20 to 30 brackets every year! His tip: the more brackets, the better your chance is to win.
     
"Espn, CBS Sports, Yahoo Sports, pools around friends, work," said Arnett.
     
Each person has their own strategy. Some flip coins, others choose mascots.
     
However, no matter what animal a team has, here's some sound advice.
     
First thing's first, fill out your bracket in pencil. You'll definitely second guess your opinion at least three times.
     
Also, never pick against a number one seed in the first round.
     
I'm all for taking risks, but they've never lost in round one, and it's not happening this year.
     
Number one seeds have also won 17 of the last 28 championships.
     
As you go down the list, be gutsy early, but sensible in the later rounds. Picking underdogs can set your bracket apart, but it can also leave you with an early exit from your pool.
     
Some big picks are upsets for seeds 5 vs. 12, 6 vs. 11, and 7 vs. 10.
     
In the end, it's not about how many hours of research you've done, or whether the coin lands on heads or tails; because this time of year, any team can beat any other team on any given day.
     
"That's what makes it march madness, it's the upsets. You don't know what's going to happen," said Arnett.

Just so you know, the odds of picking a perfect bracket are 1:9.2 quintillion. That's a nine followed by 18 zeroes.
