Heard the Tom Brady podcast the other day in which he explains that changes in the rules driven by player safety concerns have made Special Teams progressively less and less significant. Bear in mind that in New England, Belichick had a super strong emphasis on ST and that was the environment where Brady evolved. It was interesting to hear him basically say that ST are now a relative non-issue. Yes, sometimes big plays occur (like the long TD Buffalo killed us in Miami), but they are the exception, not the norm.
I get the impression that McDaniel would concur with TB12. He'd like a more from Special Teams. Jason Sanders had a good season as a reliable kicker and he seems to like Crossman on his coaching staff. However, another poor season will probably see Crossman fired.
