Yeh exactly- I see Shanahan having staying power w/that scheme because he understands offense on a better level imo. McVay got away w/misdirection and a real talent for designing effective timing routes helped a lot by the threat of Gurley at pretty much any moment. That's only going to be effective for so long tho...those windows get peeked through and buttoned up once enough tape is out. Shanahan's offense is really great to watch because he understands the micro- and macro levels of balance matchups and leverage...his feel for how a defense will respond to particular motion or formation and how to counter that is really second to none imo. From play design to game flow management the Niners are a very solid unit, I actually compare how they operate to our McDermott/Frazier defense this year. No standouts outside White and Kittle but a comprehensive understanding of strengths and an innate ability to put the right players in positions of success.
