Cleaning house would be a mistake but "tweaking" is what is needed. IMO, we will have a healthy DC next yr. The O-line has improved but they can still use a good solid LT and center. Also, a late to mid round pick on a QB would be nice. How about drafting Ty Moss from the U later on too. Yes, I know Ricky will be there but he could literally be gone agin in a puff of smoke. Hagan should be better w/another yr. I also think the secondary will be improved afet another yr w/Bell and Allen as starters. Probably we can look at LB and corner as well.
I am iffy about keeping Mularky ac OC. He may have to go, too inconsistant and abandons the run too quickly. Maybe take Jason Garrett or try to get Rob Chudzinsky from San Diego as OC.
No to trading McMike and Chambers. They had a rapport w/DC that should be goog to go next yr. Also have to keep in mind the salary cap ramification.
