Quote:I know in the case of the Raiders....they were coming off of a year in which they had a stellar running game few years back...then they had a coaching change and the new guy hired OC Gregg Knapp who switched the blocking scheme to a ZBS....and the Raiders running game, with the same personnel, struggled badly to gain YPC - and that was with all of the RB's....just like we have been seeing since we switched over to a ZBS.

I'm no expert on blocking schemes but it seems like a type of deal where you need certain personnel to make the scheme work, which of course can take time. Kinda like switching from a 4-3 to a 3-4. It doesn't really make sense in that context for the Raiders (and us) to make a switch like that when the blocking scheme was already working.
