Having Gonzales and Hunter both as top tier CBs is great in theory, but it's not how they should be constructing there team. Your also talking about paying both these guys around a total of $60 million combined a year when there rookie deals are up in a couple years. Just not a good way to allocate resources.
Id also argue that pass rush is just as important if not more important than pass coverages. Starting in the 2003 AFCCG l, every year that has gone by the NFL madw it harder and harder to play pass coverage and tilts the game more towards the QB, WRs and Offense. The only effective way to combat that is with a good pass rush
