The Chicago Mustache Theory is in effect.

Since 1986, three Chicago sports head coaches have won championships, and they have all had one, very furry thing in common —— a mustache.

With the Bears, Mike Ditka won Super Bowl XX and has been feared by all ever since. Before Ditka, the Bears hadn’t even won a Super Bowl, but they did win the NFL Championship in 1963.

Why do you think Lovie didn’t win it?

Phil Jackson was victorious in six NBA Finals in the 1990s with the Bulls and has gone 0-2 ever since moving his ‘stache out of town. Prior to Jackson’s arrival, the Bulls hadn’t even made the NBA Finals, let alone win a championship.

In 2005, the White Sox won the World Series with Ozzie Guillen’s loud mouth at the helm. Before Guillen, the White Sox hadn’t reached a World Series since ‘59 and won one since 1917.

These coaches turned their franchises around and brought a champion-like feel to the city with their lip ticklers.

Three out of the four major sports in Chicago have won championships with their coach looking like Burt Reynolds, but there’s still one to go —— hockey.

About four months ago, a man by the name of Joel Quenneville was named as the Blackhawks’ new head coach. And what is donned above this man’s mouth do you ask? Some upper lip plumage.

The Blackhawks haven’t won the Stanley Cup in almost 47 years and fans are getting pumped up with these kids named [Patrick] Kane and [Jonathan] Toews.

Currently the Hawks are fourth in the Western Conference and are on the way to grabbing home ice in the first round for the first time since 1996. Just wait until April when the entire team has some facial hair.

And what about the Cubs? What can erase 100 years of losing? How about a mustache, Lou? It’s your turn. Grow a cookie duster.
