I guess this is why I am ok with giving him a three year deal. Even at 3 years, 18 mil if you draft and develop his replacement, it isn't financially punitive to keep both or just cut Fro. And yes, none of these players are irreplaceable but I also don't want to spend prime draft picks on the replacements. I am fine with the Cardinals spending 20 mil to keep Conner, White, and Fro if they aren't going to spend 20 mil on an EDGE rusher or DL (which there is no indication they are interested in doing so).
As I have said in multiple threads, the roster is bare for young talent that will command large contracts, and as long as the Cardinals continue to be frugal in FA, they are basically operating like they have a QB on a rookie deal over the next two seasons. This year is a prime example. Cardinals signed two DL and a starting CB in FA and they still are sitting on 35 mil.
