The Big Ten was dominated by upperclassmen in 2013.
Of the 27 players elected to the Coaches' All-Big Ten first team, only two—defensive ends Shilique Calhoun and Randy Gregory—weren't juniors or seniors last season, and both of those guys could have declared for the NFL draft had they chosen to in 2014.
With so much talent leaving this offseason, the door has been opened for certain underclassmen to step up and take the conference by storm. Whether the leap they take is from decent to good, good to great or great to phenomenal, those who improve have a chance to become the class of the league.
With so much young talent to choose from, it was hard to whittle the list down to five. I focused on players who won't just improve, but whose improvement—or at least the magnitude of that improvement—would be the most profound.
I don't hate your team if it doesn't have a player listed. I swear. But these are the five guys, in my opinion, who could most shock the conference in 2014.
