ok my thought is this
1) we are uncertain how slot CB pans out meaning Sutton may be forced to play it instead of outside
2) Haden is 32 years old and injuries creep in when you get to that age ....
3) Pierre has very little experience
so if 1 and 2 happen you have just 1 inexperienced CB to throw into the mix on the outside without calling Justin Laynes number , and if Laynes number is called for any length of time the season is over IMO....
If Just 1 happens its a toss up to weather its Pierre or Witherspoon get the call ...
He instantly becomes the fastest CB on the team and he is long and rangy , he has the traits and has some very good film ( and some ugly film but that was prior to the good tape ) his arrow presumably is pointed up and for a late round pick that historically has produced nothing for the team its well worth the gamble even if it is 2 late round selections ... 2 nobodies for a somebody is almost always a good deal
