Probably best not to parse the exit interviews too much. Guentzel's a smart guy, the "would love to stay, but we'll see what happens" line is just what an agent would coach a big-time pending UFA to say.
On the 32 Thoughts Necas report, Friedman is definitely more cautious as an insider compared to Dreger or Seravalli. So I'm not surprised his other updates weren't all that illuminating, but he speaks more definitively on Necas.
Waddell on the other hand, we all know he loves to negotiate through the media. It's just the correct posturing from his position to not even suggest we wouldn't sign Necas long-term. But we've seen how Necas has been used as a potential trade piece multiple times (Tkachuk, EP, etc.) and there's enough smoke to see the writing on the wall.
I'm conflicted because I think there's room for a high-variance guy like him who doesn't necessarily fit as a typical Cane, but has that game-breaking skill that you need when the rest of the squad doesn't have it going. But with Jarvis (sometimes Svech) on the right side, and right-shot prospects like FUS, Nadeau, and Blake, it's probably the easiest position for us to deal at the moment.
