It's preseason, the same Panther team that got beat by Miami and the Bungles, also did convincingly beat a good Giants team in week 1, does it mean anything....no.
As it was said before, our biggest measuring still will be on Saturday against the Bucs, and even then, don't take it too seriously, because I don't think the Dolphins will be preparing for the Bucs as much as continuing to prepare for week 1 against the Pats in practice. Miami has little time to get ready with it's new offense, so they are going to prepare for the real games, and throw very little out there in pre-season for the Pats to watch and get ready for.
Sparano will just be watching for general effectiveness with a pretty vanilla Offense, and take it from there who makes what mistakes, and who looks better, as well as any position that is still being evaluated (Safety.....RT.....LG....nickle and dime DBs)and go from there.....it's all about and only about the Pats game, remember that when watching the game against the Bucs.
