Another month has come and gone, and with it comes another new rankings with no similarities to the previous one. I cannot recall a time when such a large portion of rookies were making such a big impact on the ice (and on the score sheets) for teams vying for the playoffs. The third edition of the Calder Watch brings its? third different number one, but it comes with some hesitation. Meanwhile, one new face has jumped into the top-10 at the expense of one of the rookie netminders. Speaking of netminders, last month?s top rookie has taken a surprising fall. Don?t Sleep On: Derek Stepan, NYR; Corey Crawford - CHI Falling: Michal Neuvirth, WSH (10) All stats as of Sunday, January 16, 2011; previous month?s rankings in brackets 10. P.K. Subban ? Montreal (9) Subban possesses incredible skills as an offensive defenseman, but he needs to improve his defensive play considerably. He has been plagued recently by a number of bad giveaways, however his January has been much better than his December so far. All three of his goals have come on the power play, and his 15 points (3G, 12A) ranks fifth among rookie blueliners. 9. Sergei Bobrovsky ? Philadelphia (1) After setting the world on fire over the first month of the season, Bob The Goalie has seen sporadic playing time since Christmas as Brian Boucher has been on a tear in the Flyers? goal. He still boasts solid numbers (17-6-3, 2.53GAA, .917SV%) and as soon as Boucher?s hot streak ends, Bobrovsky could see regular playing time once again. 8. Jordan Eberle ? Edmonton (3) My preseason Calder pick is currently on the shelf nursing a couple of injuries; while resting an ankle sprain, he had to have his appendix removed on January 6th. It?s unfortunate as Eberle was having a great season, but the depth at forward among rookies is so steep that any time missed will edge one out of consideration for the year-end hardware. His 23 points (in 37 games) ranks tied for sixth, while his 34 takeaways are still good enough for first. 7. Bryan Bickell ? Chicago (NR) Chicago knew it would have to count on some rookies this season because of their salary cap trouble, and Bickell has played far better than anyone in the organization could have imagined right away. He only had 31 points in 65 AHL games last season, so no one expected to see him put up 24 points (11G, 13A) in his first 43 games this season. Bickell also sports a very tidy +10 rating and leads all rookies by a wide margin with 105 hits. He also has an unheard of takeaway-giveaway difference of 25-3. The second round pick in 2004 is certainly helping Chicago nudge back into the playoff picture in the crowded West. 6. Cam Fowler ? Anaheim (4) Fowler is doing his best to limit the damage of Scott Niedermayer?s retirement in Anaheim, leading all rookie defensemen with 20 assists, 23 points, 22:19 of ice time per game, and 11 power play points. Unfortunately his -10 rating brings him down, but it?s still hard to understand how he slipped all the way to 12th in the 2010 NHL Entry Draft. My guess is, there are at least nine GMs second guessing themselves. 5. Kevin Shattenkirk ? Colorado (7) Despite only playing in 33 games, Shattenkirk is second to Fowler in points (20) for rookie defensemen, power play points (8), and is tied for first in goals (5). Shattenkirk edges Fowler based on the OCPR ranking (100.464 edges out Fowler?s 93.5525); the ranking difference likely comes from his -4 rating, along with his 24 takeaways compared to just 15 giveaways. I don?t believe Colorado would be currently sitting in a playoff spot without the contributions of Shattenkirk. 4. Taylor Hall ? Edmonton (8) Hall has six points in his last nine games, including the first (of many to come, I?m sure) two-goal game of his career last week against San Jose. The 2010 1st overall pick ranks third in goals (14) and points (27) by a rookie while logging the most ice time of any other forward (18:15). Despite his speed and ability to track down the puck (33 takeways), Hall has only taken five minor penalties. His -6 rating is offset by his 24 blocked shots (2nd among rookie forwards). 3. John Carlson ? Washington (6) Carlson seems to get better every game, as coach Bruce Boudreau is now using him on a shut-down pairing against the opposing teams? top offensive players. His five goals ties him with Shattenkirk on top, and he is second in shots (81) and ice time (22:01). His +14 rating is best among all rookie defensemen, as are his 87 blocked shots and 30 takeaways. His OCPR of 118.933 is more than 18 points better than Shattenkirk. 2. Jeff Skinner ? Carolina (5) Skinner is on some kind of tear right now, with points in five straight games and 12 points in his last 11 games overall. Skinner, the 7th overall pick in June, is a large reason the Hurricanes have narrowed the gap between themselves and the top-8 in the East. He leads all rookies with 20 assists, 36 points, and 12 power play points, and does it all in only 16+ minutes of ice time. Though he is young, he takes great care of the puck, with a TA-GA ratio of 26-15. Only Couture has more goals than Skinner?s 16, but Skinner has taken 41 fewer shots. 1. Logan Couture ? San Jose (2) While the rest of his teammates have struggled mightily, Couture has tried to put the Sharks on his back. Despite his team having four Olympians in the 2010 gold medal game, it is Couture who leads the Sharks (and all rookies) with 19 goals and 5 game winners. And while four of his high priced teammates have a plus/minus worse than -10, Couture is +9 while proving to be a very capable faceoff man (51.8%). Tack on his five power play goals and a good TA-GA ratio of 21-13, and Couture has a very slight edge on Skinner at the moment.
