Just give it some time man. They are going to sign 4-6 guys in free agency and I think at least two of them we'll all be happy with. Filling out the training camp roster is of very little importance right now. The focus for the FO has to be spending smart money in free agency and spending every moment possible deciding on a QB.
Letting Levitre go of course sucks but was probably the prudent decision. We've secured some time to work on Byrd, signed McKelvin, fortunately Kelsay retired, we made some smart non signings in Jones and Nelson (I believe his injury is a real problem), and made some necessary cuts in Barnett and Wilson. New coaching brings in their own type of guys. Lets allow this to play out before we say for sure their not doing the right things.
