If Ronnie Brown is healthy and back in his 2007 form, he will gain some cache as the only legit star on the team from years past. I don't think he is a great interviewer, but he isn't bad. So he will have the skills and the national recognition to merit camera time on ESPN
Interestingly enough, if Jake Long steps up quickly, we could have a LT spokesman. He is one of the most visible Dolphins who will have national recognition because of his draft status.
Of course, whoever is QB will be a natural choice, but if he only plays mediocre football, than he won't qulaify. If he does well (whchever one he is), he will immediately step into the role of spokesperson because there is really no one else.
On Defense, Joey Porter perhaps.
Just so long as Jay Feeley isn't the spokesperson!
