This is a punch in the gut to Miami's offense.

Running back Lamar Miller, the second-leading rusher in the ACC, has decided to forgo his final two seasons of eligibility and enter the NFL draft. Miller is ranked No. 30 in Todd McShay's latest top 32 draft-eligible players, and McShay writes that Miller appears "ready for the NFL."

Apparently he agrees. Miller's decision shouldn't come as a huge surprise, considering how highly he is regarded by many draft experts, but that doesn't lessen the blow to Miami's offense.

It's not like the Canes won't have any depth at the position -- they've still got Mike James and Eduardo Clements, redshirt sophomore Darion Hall, and any incoming recruits who could contribute immediately. The opportunity for immediate playing time could also be a selling point on the recruiting trail. There's no question the Canes will be missing their primary ball carrier, though, next year, and the ACC will be missing a potential Heisman candidate.
