Richie's apparent lack of form during last year's Tour was concerning, though perhaps this was more based on lack of incentive once bad luck/positioning (and Pogacar) had taken he (and his teammates) out of contention. He did of course have good form in the early season, culminating in that Dauphne victory. If he takes that sort of form to the Giro then who knows? Weak field, and often an unpredictable race. Going there as the number 2, maybe he can Carapaz Carapaz 
He also is aiming at T-A, as this is the rare one week race not on his palmares.
