miss the point. a star closer is nowhere near in value to an ace starting pitcher. you could offer Riveria in his prime and you'd still need a ton more to acquire Felix. if Feliz can be converted into a good starter, it's a whole other story completely but right now, an "elite" closer is not worth anything compared to an elite SP.
i don't think Andrus is going to get that much better than he is now. that said, he's a 3 WAR (so far this season) SS, a really thin position.
i hope you didn't just cite W/L as a stat to talk up a pitcher. and a sub 3 era looks great...but he's got an xFIP closer to 4. Ogando isn't this good but he's still a decent mid to back end starter.
he's already got a Cy Young and over a thousand strikeouts at age 25. he is coming off back to back amazing seasons. he is a ridiculously good pitcher signed to a very friendly contract given his performance. you don't trade Felix Hernandez for B players like Feliz, Andrus, and Ogando. conversely, if that deal gets it done for your team to acquire Felix, you pull the trigger. quickly. before someone tells the Seattle GM he just got swindled.
he doesn't strike batters out, here or in the minors, doesn't show good control, and doesn't have any true plus pitches. he's a back end guy, especially in the AL East.
