While that may be true, you know as well as i do, that Vuelta stage wins do not compare to TDF stage wins. So, nice try there ;-)
I'm not saying Van Avermaet shouldn't have been more successful, but i think he also wore the yellow jersey a lot more than Porte, (the GC guy) did. And especially in 2016, your argument falls flat. While he may be an underachiever in some ways, he also races throughout the entire season and has given his team a lot of exposure (which is what the team needs).
And my point was that stage 5 of a TDF in 2016, while Porte has proven zero *** as a GC rider while Van Avermaet was in his best ever form, you don't have to make such a fuss about the team protecting their star rider (whether you like to hear it or not) who ended up winning the god damn stage. But as far as the team goas, i agree, it should have done better to prevent such time loss for their GC rider.
Since Trentin is the better finisher and 4 years younger, chances are it's Trentin. But what does that have to do with anything?
The relevance of me including Gilbert in the discussion is to show how difficult it is for top level classic riders to win GT stages, unless you are a top level sprinter, while in today's area of specialisation, fast sprinters play a limited role in the classics - So if you build a team around a Classics rider GT stages will be hard to find - Finally, Gilbert's 11 GT stage wins is not to be under-estimated.
