Last year's Vuelta was super interesting due to the compressed World Tour calendar and everyone riding not knowing if it was their last race all season-long, but I'm not that hyped this year. If Pogacar were competing then I would've loved to follow a Rog v. Pog v. Bernal clash.
Supposedly Bernal is still having back issues, so Roglic is the clear favorite minus his tendency for misfortune (which should really be defined on a scale with units in Geraints; I'd rate Roglic a 0.7 G).
Of course the unpredictability of any Grand Tour without a dominant rider and team means the compellingness of the Vuelta could turn on a dime at any stage. I hope that does indeed happen!
