First, bless Feldman, but his relationship with Mario is superficial. He's a media guy who happened to be at Miami when Mario was on campus more than 2 decades ago. That's a returned phone call and an ice-breaker. Feldman now gets paid to speculate and, like the rest of us, try and put 2 and 2 together. Sometimes he's good at it, other times not so much. Not buying his idea of Mario jumping ship for USC, unless they throw an ungodly amount of cash his way.
Second, as said elsewhere, it's too early to determine how this plays out. Both Oregon and Miami have seasons to play out. If things go well for Oregon, Phil Knight's underlings will determine how much they like Mario and what he's worth. Miami has to first decide who's really making decisions. What do they do with Blake James, what's owed Manny, what's Mario's buyout at Oregon, what's the potential salary for Mario and his staff, and where do they get the money from.
Again, it's 3 weeks into the season and it's pure speculation on what might play out in January.
