Yeah see I don't see it that way - none of those things answer the question at all IMO.
Hopkins was not happy and never would have played for us.
Passing up a pass rusher for a tackle makes a lot of sense - first off the likelihood of hitting on an OT is far higher than a pass rusher, and a new GM is going to want the surest pick available when he is starting his new job. Also in my opinion tackle is just a more valuable position.
Simmons was continuing to make mental mistakes and was a likely cut if not traded.
When you are choosing whether to resign a player or not, there is more to it than are they just good - first off they need to fit the new coaches schemes, 2nd it has to be determined if the price to retain them is worth it in the situation you are in - and most importantly they have to even consider resigning with you - it's not like they were restricted.
Colt McCoy was coming off an injury and looked horrible in camp - cutting him has nothing to do with tanking, it has to do with him being bad.
Not signing free agents of any significance makes sense at the start of a rebuild as well, because the only way you can sign them to an unknown coaching staff and a team with bad talent is to grossly over pay them. It makes far more sense to pay them after you have made your situation better with some an up and coming young talent.
