Vuelta a España 2019 stage 14: San Vicente De La Barquera - Oviedo > 188km

I'm warming up to this Vuelta, the stage shouldn't have GC ramifications, although an uphill sprint finish could get Valverde a puncher's chance to get a time bonus.
Why don't the GC teams come to an arrangement with the four or five sprinters, and then let them and their helpers get into the break and make it an easy day for the GC teams.
