First, forwards who have played at least 100 minutes minutes overall at even strength. This excludes 5 players (Devane, Leivo, Broll, Abbott and McKegg):
F/20, A/20 and N/20 are the even strength chance rates per 20 minutes ice time.
Jerry D'Amigo definitely seemed to deserve another shot at the NHL, as he was very effective in his relatively limited time, the only Leaf who was on for more chances for than against.
Nazem Kadri led this list at the halfway point, but has fallen behind the players on the big line, with Phil Kessel pulling up to lead the current roster in percentage and in chances overall. The big line is the worst defensive line, but is also on for farm more chances against than any other set of forwards; Kadri is almost as poor defensively, but generates almost a chance/20 minutes less than Kessel, and Raymond and Lupul generate two chances/20 fewer.
Nik Kulemin continues to impress, posting a differentialy almost as good as the top line players, and it certainly seems like any move to trade him, while keeping struggling chance players like Raymond and Lupul, would be a big mistake.
Joffrey Lupul has consistently been the most disappointing forward on the team, really struggling to generate chances, despite being moved around in the lineup; separating Kessel and JVR seems to be insane, but if one of those players could be effective without another, it might be worth it to jumpstart Lupul.
The return of David Bolland will be an interesting point, as it's not clear what level of play he'll manage after his return from injury; if he can be around the 47% level he put together while healthy, it would be a big boost, reducing the ice time of players like Smith (43%), McClement (41%) and Holland (41%).
The big three have been the best offensive performers on the team, with Kadri the next best in terms of generating chances. Defensively, the best numbers belong to the low-event fourth liners, along with the injured Bolland; other than those players, the best is the aforementioned Kulemin.
I also put together some data on forward lines:
These have some pretty small sample sizes, but here's every line on for at least 20 total chances (unfortunately, I don't have icetime for these line combos).
Kessel and JVR are the key to the Leafs' two consistently effective lines, but Kulemin also has been useful with McClement, whether Clarkson, D'Amigo or Raymond has been the winger. Holland-Lupul-Raymond has beeen a really poor line, and Holland was much worse than Kadri with Kessel and JVR.
Next, the defense:
Gunnarsson continued to be the top defenseman, but the addition of Gleason has been a clear positive, as he slots in close to Phaneuf in terms of performance. Reducing the burden on the likes of Franson and Ranger has an excellent result, and Gleason has been an excellent addition (for comparison, Liles was at 43.8% this season).
Cody Franson's poor season continues, as he remaines mired at the bottom of the team percentages, not generating much offense and having one of the worst defensive records as well. Rielly is on for as many chances, but is one of the better Leafs at generating chances.
It's pretty clear that using Franson with Gleason has been vastly superior to using him with one of the rookie defensmen, who had been his primary partners to this point; The Leafs can now actualyl put together three solid ES defensive pairings in Phaneuf-Gunnarsson, Franson-Gleason and Rielly-Gardiner, as all three of these partnerships have been over 48% when on the ice. It's the likes of Franson/Gardiner and Franson/Rielly, along with Ranger/Gardiner, that have been troublesome.
