Trade Deadline pickups can make impact

The NHL Trade Deadline has come and gone. The underlying numbers can help sort it all out, and provide an interesting perspective on how some of these transactions can affect the final quarter of the regular season.
Let's examine five interesting stats for players who have changed jerseys recently:

Thomas Vanek, RW, Florida Panthers
Even-Strength Scoring Rate: 2.80 points per 60 minutes
The Florida Panthers rank No. 22 in the NHL with an average of 2.48 goals per game and are one point out of the second wild card into the Stanley Cup Playoffs. The acquisition of Vanek from the Detroit Red Wings could be just the scoring boost the Panthers need down the stretch.
Given individual variations in ice time and opportunities to play on the power play, the clearest way to establish a player's offensive performance is with his 5-on-5 scoring rate. Vanek has scored 25 points in 535:53 at 5-on-5 for a scoring rate of 2.80 points per 60 minutes that ranks third among those who have played at least 500 minutes, according to the data compiled at Hockey Analysis.

The Panthers are hoping this represents a return to form for Vanek, who ranked seventh in the League with a 5-on-5 scoring rate of 2.63 in 2013-14. If so, Vanek could have the same impact in Florida as he did for Montreal when he was acquired from the New York Islanders on March 5, 2014. Vanek had 15 points (six goals, nine assists) in Montreal's final 16 games, helping the Canadiens finish the season on an 11-4-1 run.
PA Parenteau, RW, Nashville Predators
Shootout scoring percentage: 43.5
Every point matters for teams in the playoff hunt, including those earned in shootouts.
That's why the Nashville Predators helped themselves by bringing in Parenteau, who has scored 20 goals in 46 career attempts in the tiebreaker. His 43.5 percent success rate is 14th among active players who have at least 20 shootout attempts.
Since the start of the 2014-15 season, the Predators are 21-for-74 in shootout attempts (28.4 percent). Parenteau's acquisition could help Nashville, who are 2-3 in shootouts this season, earn a couple of additional points down the stretch.
Kevin Shattenkirk, D, Washington Capitals
SAT: Plus-88
When he was acquired by the Washington Capitals Feb. 27, Shattenkirk was leading the St. Louis Blues with an SAT of plus-88. This statistic is the even-strength differential in shot attempts, in which the Blues were beating opponents 786-698 with Shattenkirk on the ice.
This success is nothing new for Shattenkirk, who had a team-high SAT of plus-958 in 425 career games with the Blues, based on a 6,284-5,326 advantage in shot attempts with him on the ice since he was acquired from the Colorado Avalanche on Feb. 19, 2011. In percentage terms, the Blues' share of all shot attempts improved from 51.0 percent to 54.1 percent when Shattenkirk was on the ice.

If this success continues, then Shattenkirk could be the critical edge that could put his new team over the top. Prior to his arrival, Washington ranked No. 9 in the NHL with a team SAT of plus-97, having outattempted its opponents 2,653-2,556.
Martin Hanzal, C, Minnesota Wild
Faceoff winning percentage: 56.1 percent
Hockey is a series of puck battles, and each sequence begins with a faceoff. Hanzal's success in that area can help Minnesota continue its push to finish first in the Western Conference.
Since the start of the 2014-15 season, Hanzal has won 1,539 faceoffs and lost 1,206 (56.1 percent). That ranks No. 11 among the 136 centers who have taken at least 1,000 draws during that time.
As a team, the Minnesota Wild entered Thursday seventh in the NHL with a 51.7 winning percentage on faceoffs. They're led by Mikko Koivu, who has won 729 faceoffs and lost 599, a winning percentage of 54.9 percent.
Ron Hainsey, D, Pittsburgh Penguins
Average shorthanded ice time: 2:59
With two of their top three penalty-killing defensemen out with injuries, the Pittsburgh Penguins were looking for help in shorthanded situations. In Hainsey, they have acquired one of the League's most experienced and effective penalty-killers.
Hainsey averages 2:59 of penalty-killing time per game, 19th in the NHL. Overall, he has seen 734:02 of ice time while his team is shorthanded since joining the Carolina Hurricanes as a free agent for the 2013-14 season; that's No. 19 in the NHL during that span.

At a team level, the results have been excellent. Carolina's penalty-killing percentage since the start of the 2013-14 season is 83.9 percent, second to the St. Louis Blues (84.7 percent). For the Penguins, who rank No. 19 in penalty killing this season at 80.4 percent, Hainsey could play a critical role down the stretch.
