bottom line - if youbouty and wright are performing as expected (or surpassing expectations) they don't need to be replaced.......it's not like they had to light the world on fire - if youbouty was a solid nickel corner people would be happy and the same for wright as a 3rd RB
those picks that were used on their replacements could have been used in a number of other areas - could have used them to trade up, to replace a free agent who left, to protect yourself for a vet who might leave after this season, to acquire future picks in the draft, etc etc...........they shouldn't need to be replaced at this point, and if they are it signals they were bad picks
doesn't really matter what round we're talking about here - the picks have value and replacing guys who should be productive is a waste of that value
