Roglic as a defensive rider? Come on now. Jumbo might have defensive Skyesque team tactics but Roglic (and Van Aert) seemed like the outliers in the team. They seemed like offensive, attacking riders, not the marginal gains guys. For my money, Jonas Vingegaard is the ideal Jumbo rider. Quiet, follows team orders, rides according to data instead of emotion and super calculated. It's probably why he's gone from unremarkable junior to the best GT rider in the world under their program.
That's not Roglic. Roglic is excitement, attacks and emotion. The one thing Jumbo and Roglic seemed like they ever had in common was a love of winning.
Which is to say- Roglic is many things, a boring rider isn't one of them.
