Chaney was at one time elite. I think he got passed by and of course he also had one of the worst stables of QBs in our history as wellLook at where our offense ranked in points per game this year compared to last and that was with a LOT of turnover on the offensive side of the ball.
That quantifies doing a lot more with less and exceeding expectations. Two totally different brands of football, but I think the difference in numbers are so significant that they can't just be chalked up to systems; not that it matters, but I always thought Jim Chaney was a great play caller, perhaps not elite.
