Grischuk, Mamedyarov, and Adams seem to be the consistent ~2750+'ers who are good but don't get much attention for it.
Grischuk experienced a rating leap in 2010 that he hasn't really looked back from -- although he reduced his volume noticeably after rising to the Candidate Super Duper De-Duper GM level. I'm curious about what he got better at. (Okay, winning and not losing, of course. But I mean process-wise.)
Mamedyarov. It's like no one even knows he's ultra strong except tournament organizers. There isn't much fanfare for him at all. I wonder too what he did to rise from fledgling 2700'er to perennial 2750+'er. Maybe just grow older? People hit their intellectual peak, wrt raw brainpower, at age 25 or so, I've heard. I'm excited about the prospect of becoming smarter.
It makes one wonder what the future holds for Carlsen and Caruana. Or maybe they are destined to be overpowered Ponomariovs.
Micheal Adams is so obscure I don't even have a blurb for him. Sorry Mickey.
