I almost have to ask if you might have mixed him up with a different prospect. That's one thing no one in Columbus would question with Sillinger. He's strong and his determination and battle level are high end.
Ya, I never had that perception of Sillinger. The issue with him would never be about grit, or desire. Just more about his talent, or offensive talent, at least. He's kind of a Ryan Hartman in training.
Rossi is definitely more of a skill player, but he had a really good summer in the gym, and came back sticking his nose into all sorts of net front scrums. There was one funny incident in Montreal where 6'3" Guhle cross checked Kaprizov, and little 5'9" Rossi(in lifts) jumped right into his face. Definitely a Jack Russell v Great Dane moment.
Again, i would be very disappointed if Rossi is traded for someone like Sillinger, who, IMO, has a lower offensive ceiling. I don't get trading for Johnson, either, as he isn't going to provide any toughness, either. If Marco can continue to get a tad faster, stronger, and most importantly, get some decent linemates, then he will be a top 6 C for MN for a decade. I don't give a damn how tall he is if he can do the job.
If you listen to Russo, he is echoing my thoughts, but is merely reporting what both he and Joe Smith (other Athletic beat writer) has heard.
