If someone wants to give up a first or second rounder, I am sure Miami will listen. If not, why trade a top 15 guy who can work in tandem with another top 15 style RB in Ronnie Brown. Sure, it sucks in the FF universe, but in the real world of the NFL two backs with that much talent = problems stopping the run for opposing defenses.
I know nick wants to get younger and better on D and on the O line, so if trading ricky can help that, he might. If not, another year of R&R.
