Extreme makeover: San Jose Sharks

Starting with the Philadelphia Flyers' bold trades just prior to the NHL draft, the league's landscape has undergone some significant changes this offseason. For the next five weeks, Insider contributor Neil Greenberg will examine, in detail, five of the biggest summer renovators -- the San Jose Sharks, the Minnesota Wild, the Los Angeles Kings, the Washington Capitals and the Flyers -- to see what we can expect from their remodeled rosters. The series starts with a look at the Sharks.

Offense was not a problem for the Sharks last season. They had the second-most points in the Western Conference, which was also good for fourth-best in the NHL. Their power play, second-best in the league, converted on a quarter of its opportunities.

The defensive side of the puck, however, had numerous issues. San Jose's penalty kill, a weakness for the team all season, finished 24th in the league, and the lack of quickness and defensive depth on the blue line led to a 4-1 series loss to Vancouver in the Western Conference Finals.

A summertime revamp, which included trading away goal scorers Devin Setoguchi and Dany Heatley, gave the Sharks a more definitive defensive presence, but did they swing the pendulum too far in their attempt to add more grit in their own zone?
