I am not defending Dennis Erickson, but he had the least amount of talent to work with , at least Nolan and Sing had some pieces to work with, but they were more concerned with putting their own stamp on the team, and create a team in their visions that NEVER panned out, both went too far in regards to discipline and both echoed "its my way or the highway" ...both Sing and Nolan had NO BUSINESS being involved with the offense, neither of them knew how to improve the offense and let OC's with no creativity run the show (Jimmy Raye, Jim Hostler, Mike Johnson
)
The Mike Martz experiment was also a disaster
We really should have made Norv Turner the HC back when we had the chance, instead we were stuck with unproven defensive minded coaches, and an alcoholic GM that didnt bring in much talent ....I;m so glad those days are over , now we have a talented coach who assembled a great coaching staff that made us a strong competitive team
