can or should the oilers run RNH at center

Ideally, but they just don't have that good of winger depth to do it really. Hopefully Holloway is ready to start or finish the season in the top 9, as you said -- that would help a lot.

I really don't like McDavid with Kassian and Hyman -- he needs a skill guy in there with him.

No

No, the best bet is to have him as the 2LW, and run him with Draisaitl, and Yamamoto. Our bottom 6 is good enough, and I don’t really want Kassian, and Foegele in the top 6. With Nuge in the top 6, he will be worth his contact, and it will give us more scoring in the long run. Also, in case if people don’t know, Nuge sucks at being a center man. I would just put Ryan there, and then start the season. I don’t care what people say, Holland is a great GM, and this team is going to be good if everyone clicks.

I think that would be ideal for Edmonton. I think it depends on how good the young guys are. I am really high on Holloway. I think he plays that similar style to Hyman but has more skill. Obviously a big ask for him to come in and produce right away, but I think he is an NHL player this winter. My ideal lineup with the young guys would be something like this:

Hyman-McDavid-Puljujärvi
Foegele-Draisaitl-Yamamoto
McLeod/Benson-RNH-Holloway
Archibald-Ryan-Kassian

The two first lines you should be comfortable running out against anyone, while the third line can be sheltered with the young guys. 4th line is your energy line.

That is why I have him mcloed. RNH has always struggled at draws the rest of his center ability is ok against top comp this allows him more sheltered role as center. mcloed can be eased in and take draws as he was pretty good inhis short stint last year. I get the Kassian part.
as for Foegele every report I heard said he would look out of place on second line as long as it has good skilled players. he would fill the same role as hyman on the first line check and get the puck to DRi and JP
