With guys like Evenepoel, Bernal, Pogacar, MvdP, WvA, you know they are not afraid to eat some wind, cause some splits and provide entertainment (reminder: watching racing = entertainment, and nothing else). If it wasn't Roglic but Pog, they were gone and the 'dumb(*)' move would have been a very good one (it's called selffullfilling prophecy, but you have those who can pull it off and those who can't or won't).
Ofcourse, like in every Western movie, besides the good guys mentioned above, you also need some bad guys (Escartin will be the ugly one) like Gerrans, Roglic, Zubeldia, Valvderd, Van Garderen... to provide extra draft for the heroes that are pulling, by sucking their wheels.
So I want to thank Roglic who seems to be in good shape, thus hard to drop and dangerous if Remco is overconfident. Without wheelsuckers like him, we wouldn't have a competitive race.
(*) dumb moves are those that make you lose the race. This move wasn't winning, but wasn't losing either. It could have been winning in certain circumstances, and there was nothing lost with trying.
