One of Randy Carlyle's major challenges as the Leafs' head coach will be implementing a defensive scheme that somehow cuts down on the massive goals-against totals that have doomed the Leafs for years.

He can start by actually teaching the team about defence, something former coach Ron Wilson felt was unnecessary, apparently. In fact, Wilson didn't teach the Leafs anything about the defensive zone when he was in Toronto, not even where in the rink it was located. Poor Cody Franson was so confused he thought it was in the press box.

To combat the utter ignorance on his roster, Carlyle drew up a map of the defensive zone to help teach the Leafs how to play defence. It wasn't supposed to be leaked to the public, but I found a crumpled up copy in a trash bin after Leafs practice on Thursday. Perhaps it was tossed aside by a certain bald-headed, injury-prone centre on his way down to the minors.

Special thanks to Down Goes Brown for the inspiration for the piece and my friend, Geoff, for his input.

Make sure you know which players are now crazy.

There are plenty of ways to make money on the internet. You can try your hand gambling by playing online poker; you could sell your vintage NHL jersey collection to the hipsters of the world on eBay; or you can dominate your friends in fantasy hockey. Yahoo! has even made it possible for people without friends to win money playing fantasy hockey.

But you can't just waltz into the online arena and expect to win money without a plan. You'll be eaten alive like the fresh fish you are.

Fret not, for I am here to help with a trusty battle guide to help you navigate the treacherous waters of draft day and beyond.

Four years ago the Leafs rushed an 18-year-old Luke Schenn to the NHL, and it looks like the team is prepared to do the same with Morgan Rielly.

“I’m gonna pick the best players,” Randy Carlyle told the Toronto Star. “If (Rielly) is among the best, I’ll have no qualms picking him because he’s 18.”

Management has echoed the coach's philosophy.

“If Morgan Rielly can help our team win, I really don’t care that he’s only 18,” Dave Nonis told the National Post. "If he’s ready, he’ll stick around."

The hope would be that Rielly could help upgrade the Leafs' blueline, one which has been near the bottom of the league for years. He is a slick-skating, puck-moving defenceman that could potentially step in and provide a reasonable facsimile of Jake Gardiner, who is currently out with a concussion.

The Leafs can give Rielly a five-game try-out (a sixth game automatically burns a year on his contract), but allowing him to make the Leafs this season, regardless of how NHL-ready he may appear, would be a monumental failure.

The most shocking Leafs news Wednesday was not a Roberto Luongo trade; it was Brian Burke's sudden firing.

Bob McKenzie first reported that Burke was being relieved of his GM duties and a press conference later in the day introduced former assistant GM Dave Nonis as his permanent replacement.
