Miami got a big contribution from an unlikely source, and there's more to the story...
The Miami Dolphins signed Jack Jones late in the offseason as their cornerback room fell apart due to injuries and general incompetence. But senior personnel executive Champ Kelly, now the interim general manager, knew him from their days with the Las Vegas Raiders, so Miami took a gamble.
Jones was brought aboard with the understanding that he'd be a bit of a boom-or-bust kind of player for Anthony Weaver's defense.
