Church is at a point in which he only has two years left on his contract, is getting somewhat expensive for what he is, and has very little dead money involved in cutting him this year or the next.
Expect Wilcox to be given a fair competition for a starting job at SS.
I think ideally the Cowboys would want Jones to play FS, and for Carr, Scandrick, and Claiborne to play corner, with White and Patmon in depth roles.
Then I think there are times in which you could ask Jones to play corner, in case of injuries or based on match up.
There are two scenarios to look at, one is the best 4 and the other is the best 5.
I think the best 4 could very well be Carr, Scandrick, Jones, Wilcox
I also think the best 5 could be Carr, Scandrick Jones, Wilcox Church or it could be Carr Scandrick Wilcox Claiborne. Comes down to who is better Claiborne at CB this year or Wilcox and Church at safety.
