I have mixed feelings on this.
I can see the Foligno comparisons, but as someone who did not the like the Foligno trade when it was made, I have more confidence in ROR. He's coming off a different injury (foot concerns me less than a shoulder) and was a far better player at his peak.
Our centre depth is now fantastic: Matthews/Tavares/ROR all bring size, scoring touch, and are responsible defensively. They're going to be very difficult to handle as a trio. Add in Kampf as 4C and Keefe can roll four lines without worry.
Where I am skeptical is the cost v. benefit. Is this team good enough with ROR to go all the way? Right now, I'm not certain. Our D is objectively good but also error-prone, the types of errors that could cost us a series. Samsonov has been fantastic this year, but whether that carries into the playoffs is an open question. We still seem to lack scoring depth, especially at 2LW. And most of all, we're likely going to have to go through Tampa and then Boston.
Odds are we are out in the 1st or 2nd round and that makes emptying the draft pick cupboard a risky move. But that is what contending teams do.
All in all, I don't love it but I can accept it, seeing as this is probably the last hurrah for this group. I would have preferred Meier though (RFA status + bigger impact, IMO).
