JEE had 4 healthy games the entire year. You don’t think Rossi ended up playing more as a result?.
When JEE was healthy Rossi was playing with Kaprizov and Zuccarello on the 1st line. I really don't think his deployment will meaningfully change over the course of a full season regardless of JEE's health. He'll play both #2 and #1 center at various times, and be demoted for a handful of games if he plays poorly. As an aside, Hynes wasn't wrong to demote Rossi, it's just that he should have done it 20 games sooner. His timing is shit.
Rossi for sure doesn’t touch the 1st power play unit if Kap and Ek are healthy. Wipes away probably at least half of his PP points.
