McDavid needs someone to play with.
Why dont they just play nuge at 3c?

Because they're seriously lacking top 6 wingers.

Finding wingers to play with McDavid, draisaitl and nuge shouldn't be that hard to do. They should be signing guys like tyler Ennis for under a million who are skilled and fast. They can get 6 wingers at a million each, let them rack up the points and let them walk so they can rinse and repeat.

Why is everyone moving Neal?

Because he's only good at accidentally deflecting pucks off his shin pads on the power play

To free up cap space. Not for the 20-21 season but the ones after when guys are coming off contracts. 21-22 Nuge and Yamamoto need new contracts and the year after that Nurse, Jones and Bouchard. Also somewhere in there is Bear's contract.

That and Nuge absolutely kills it when playing winger to one of the Hart candidates. Since he started playing LW for Draisaitl Nuge has been 5th in scoring in the entire league.

Bouchard's deal will most likely slide this year, so he still has 3 years of ELC to go. But your point stands.
