I for one have and always had full confidence in our coaching staff. Were very lucky to have the GM and the head coach that we have, they are both the best at what they do. So, I have to think that their feeling is that the zone-blocking fits our personal the best.
They obviously took a look at Denver's success with the scheme and decided to apply it. My suggestion for them would be to take a look at the Titan's scheme and see if they can use it. The Titans have a great ol coach in Munchak and have a great running game. Their o.l. might just be more talented than ours but I love the way they run the ball and wish the Texans can copy what they do. This is afterall a copy-cat league.
The running game is the only thing right now keeping the Texans from being a dominating team, its a must have to reach the super bowl. If we can somehow improve to around avg. 4.5 a carry well be in for a sweet ride.
