Malachi Toney gave Miami the kind of moment that can define a season. Now the Hurricanes are on the verge of reaching the top of the college football rankings for the first time in more than two decades. The sophomore wide receiver came through when No. 3 Miami needed him most, catching a 3-yard touchdown pass from Darian Mensah in the second overtime against Florida State before throwing a two-point conversion to Cooper Barkate. The unconventional finish proved decisive in the Hurricanes’ 43-35 victory over their longtime rival Saturday night at Hard Rock Stadium.  For Toney, a hometown star playing on one of college football’s biggest stages, the performance was a showcase of the talent and confidence that have made him central to Miami’s unbeaten start. For the Hurricanes, it was an emotional escape in a rivalry game that threatened to derail their season before delivering an opportunity to take over the No. 1 spot in the Associated Press Top 25.
