A few years ago, Miami had arguably the best cornerback tandem in the NFL (and possibly of all time) in Patrick Sertain and Sam Madison. Figuring he had a couple of years at most left in him, Dave sent Sertain to KC (4 years ago). And then Nick thought Madison didn't fit with the type of defense he wanted, so he let him go off to New York (3 years ago).
Sertain still harrasses receivers as an every down player, and is nearlyt always at the top of the heap in interceptions. Madison is more of a role player, but is still playing at a high level. And he has a SuperBowl ring.
Meanwhile, in Miami, we're looking for corners.
I guess the coaches of years gone by really didn't know talent AT ALL, did they?
