CORAL GABLES, Fla. — The leading rusher in the nation, one of the most talked-about quarterback debuts in recent memory, and even a first-place vote in the Top 25. If nothing else, Week 1 of the season might have given the Atlantic Coast Conference plenty of cause for optimism. The statistical samples after just one game are obviously small and skewed, so it's clearly not time to pronounce Miami's Duke Johnson as the season's rushing champion, anoint Florida State's Jameis Winston as a Heisman Trophy hopeful or pencil Clemson into the national championship picture.
