Turris is good offensively. Granted, he is good in more of a complementary way, in that he can skate and think and make plays at a top-6 level, but definitely benefits from having wingers who are the real drivers. But if he was any better than that, he'd be a 1st line center, not a 2nd line one.
I still don't think of him as a "desirable" asset, just because of his softness, basically. I'm a little old school like that. But that's me. Just on offense alone, though, he's entirely reasonable. And rather than fitting on " very few good teams", he's more like a player who would fit better on worse teams who don't actually need a be-all-and-end-all solution in that spot. Give him more icetime and more PP time and he'll produce. He's not old at all, and doesn't look or play like he is. He was the same player at 30 as he was at 25. I don't want him on my team, mind you. But he's still a better player than these threads are giving him credit for.
