Cycling is a team sport, for Jonas more than Pogi (who more or less can handle himself), I would say more than anyone else...
And looking at present state of affairs at Visma, strong forces leaving the team, injuries galore, and now most recently downright critics from the Giro team's GC guy about the team tactics, Plugge's monopolistic ruling, etc..
A month before it gets loose I regard this as some of the very worst conditions for Jonas, regardless of whether he has rocket legs installed or a 100% concussion recovery for the cobbles stage.
