Somebody said they liked how Stephenson looked with Eller. Could try that, with Connolly moving up to the 1st line like today, and Gersich/whoever stepping into Stephenson's place on the 4th line.
Makes sense to limit changes, especially initially, keeping existing lines or at least lines/combos that looked decent before.
In any case, it will be interesting to see. Without Wilson's intensity, I think the Caps are significantly more likely to have a rough start to the season, but it should work out just fine long term.
