As we head into Week 4 of the college football season, top teams and standout players are beginning to emerge. Sure, Johnny Manziel and AJ McCarron received most of the Week 3 headlines following the Texas A&M-Alabama shootout in College Station, but those players and teams were far from the only ones making bold early-season statements.

Who has been the best player in the nation thus far? Insider's panel of experts weighs in on that and other big questions heading into Week 4, including which players have emerged as Heisman sleepers, how Ohio State should handle its QB situation moving forward and how the five power conferences stack up.

1. Who has been the best player in college football through Week 3?

Kevin Carter: Johnny Manziel. In an offense that has averaged more than 600 yards per game, he has picked up where he left off last season. Athletes speak of the period of time where your ability meets your knowledge and understanding of the game -- where everything seems to slow down. He clearly is well beyond his years in this department. And despite all of the negative publicity in his private life, he is every bit the captain and emotional leader of this Aggies team. His teammates would follow him anywhere. Oh, and one of those 600-yard performances by the Aggies offense was against college football's best defense in Alabama.
