If Second-year defensive lineman Phillip Merling can be tough against the run and effectively rush the quarterback, he has an opportunity to start.
Vonnie Holliday was more than the Dolphins' dependable defensive end.
He was an example for their young linemen -- and, more specifically, Phillip Merling -- to follow.
With Holliday as their starter, the Dolphins could keep the training wheels on Merling, a second-round pick out of Clemson.
The rookie took roughly a third of the defensive snaps and was solid, but far from spectacular. It was his time to learn and develop as a player in the hopes of someday taking over the starting role.
But when the Dolphins and Holliday parted in March, it was a clear sign that the future is now, if Merling can handle it.
