I couldn't agree more, that is why the offensive line is important. I keep saying i want to see speed in another RB. I do like Dunbar, but I wouldn't mind another RB that is really a burner. I think they need another WR that can run a 4.3 and catch, but I don't want to speed a 1st on a player like that and that is most likely is what you will need to speed. The TE position is serviceable at best now with Witten, but they do have Escobar and Hanna.
In regards to the defense this is what you get with the Tampa 2. I want to see fast CBs that can really cover, but that again may force you to spend a 1st or 2nd. The Cowboys need to gather more picks and focus on the DL. They need at least 6 linemen to rotate and generate a pass rush. This is where I am ready to see a young coach to come in and come up with new ideas while learning from the current coaches about the 4-3. I just want to see new ideas. People have figured out the Tampa 2 and when you don't have great players on the defense it's easy to just out scheme and out play the defense. Well Rome wasn't built in a day and while other teams have done so, I don't believe Jerry and Co. are equipped to do the same. JMO.
