By severely underestimating the difficulty of the putt.
I actually recall telling my wife when they said left center that Rory was aiming way further left than that, he probably aimed 6 inches to a foot left of the hole.
Rahm thinks if he hit it on Smiley’s line from the broadcast, Rory putts it off the green.
