GF% from this season, all our centers Raymond has played with:
Larkin 37.5% with Raymond
Copp 35.0%
Ras 33.3%
Suter 62.5%
Veleno 33.3%
So he does not work with anybody, except Suter.
Larkin 59.3%, without Raymond +21.8%
Copp 60.7%, without Raymond +25.7%
Ras 46.1%, without Raymond +12.8%
Suter 38.9%, without Raymond -23.6%
Veleno 55.9% without Raymond +22.6%
So he does drag all the teammates down, expect Suter. Why aren't they locked together?
Berggren is the best opposite winger for him, then next best Perron.
Berggren/Perron - Suter - Raymond should be the starting point to build a best possible line.
Your analytical skills are as sharp as ever I see.
Completely ignoring the 3rd part of a line is not a good idea when trying to device a line-up IMO.
Take for example Copp. I would say Raymond and Copp works well together. Copp + Raymond did well when playing with either Berggren or Bertuzzi as the 2nd winger. However dragging down the numbers with Copp is the Erne + Copp + Raymond line, and the Zadina + Copp + Raymond line.
Not so surprising. Copp is a good defensive player, but in order for a line with Copp to work, you need either 1 superstar offensive player (e.g. Panarin) which the wings have none of. Or 2 Offensively-minded wingers.
When it comes to Larkin and Raymond, I think you are right, in the numbers there's a lot of context missing, such as Raymond playing with Larkin either during the hardest part of the schedule (December + January), or when Larkin was playing with a semi-hurt hand, Bertuzzi being rusty etc. But the sample size with Larkin is large enough to say that Raymond probably shouldn't be with Larkin (even-though we did see it work last season and at points this season).
The Rasmussen, Suter and Veleno data is just not enough especially if you want to look at GF/GA.
Both Rasmussen and Veleno have been on the ice for 1 GF, and 2 GA with Raymond, leading to that 33.3%. The goals could be from a poor-line change, a post PK situation or similar. The sample size is so poor that you should be ashamed for using it.
When it comes to Suter it's quite funny that you want him to be Raymond's center. Most of his time playing with Raymond, he was the 2nd winger, and Larkin was the center. But hey, why care about context.
