Zone blocking scheme outdated?

There was an unusually big man playing NT in the 3-4 for the Jets Sunday, Kris Jenkins is reportedly 360 and he actually looked bigger than that and I
know he looked much bigger to Texans center Myers. But whoever is lined up on that guy probably is gonna get pushed around and yea, get knocked down with one swat of an arm from that big grizzly.
Sometimes offensive lines have problems because they are too big and immoble vs smaller quicker DLines. For example I just checked the Titans web site which lists their starting DLine at < 280 iibs and we know that the Colts have historically also had smallish but very quick DLineman.The Texans smaller than average OLine (it's not really that small, but neither is it a large line) didn't have the problems it had because of its size or because it was running the ZB system, it had the problems because HC Kubiak and his assistants totally blew it in their preparations for the game. They played these guys last year and knew (or should have known) what was coming and got the line ready for it. Next summer, if Kubiaks still here, maybe he'll concentrate on getting his team ready for the season-opener instead of talking about how they were gonna be in the playoffs ?
