Well, that "good reason" is itself often entirely debatable, no? But frankly don't get me wrong here, i.e. I do not care enough about Van der Poel either way to go into further long-winded dissections of the how & why I think the way I do.
I'll just say as a spectator my heart sank yesterday when I saw him take off at the top of the Poggio because I knew in my bones what I was seeing, especially with the stark juxtaposition of VdP's form in Strade & Tirreno versus the monster we saw yesterday. Some people might enjoy the spectacle, I didn't. For me the suspension of disbelief was broken for those few minutes.
And I'm no downbeat cynic sh*tting all over cycling either, or falsely taking a moral high ground, i.e. I'll admit there are situations where a juiced spectacle can be... spectacular? Yesterday wasn't it. It was a mugging of the highest order.
