Callahan is so overrated but must have been doing something right since the Raiders were the most explosive offense that season.
Brown and others have questioned Callahan as a HC but I don't believe anyone doubts he knows his X's and O's.
If anything, the guy that the Cowboys should bring in as QB coach is Rich Gannon. Unlike Wade Wilson, he was a mobile QB who led one of the most explosive offenses to the SB.
