I dont see Nuge or drais staying as the #3 C. They need to make a trade before one of them leaves the oilers or demands a trade when or if all hell breaks loose again in Edm.
Why do they need to make a trade? Good teams play to their strengths, there is no "single formula" to success. You need good players utilized to their maximum potential.
Our division features teams with excellent top 6 lines and elite Dmen. At most, Doughty/Vlasic/OEL can be double shifted and take away 2 out of the 3 lines. Likewise, teams like ANA and LAK can match up their best 2 lines against our best 2 lines.
If there is a chink in the armour for teams like the LAK and ANA, it's their bottom 6. Matchup against McDavid and RNHs line, you leave Drai with a mismatch. Matchup against McDavid and Drais line, you leave RNHs line with a mismatch.
Rolling the top 9 with basically 1a, 1b, 1c style lines plays to our strengths. Wave after wave rolling those 3 lines through. Give the 4th line minimum even strength time, maybe work them in every other rotation through the top 9. Ask the 4th line to play heavy PK minutes.
In any sport, good teams utilize their strengths and create favourable situations from the personnel they have. For us, it's having 3 elite centres who can carry their own line going forward.
