Someone else did the legwork for me:
Fast forward to 2004, Atlanta. Jim Mora Jr. is hired as HC and his first hire is Alex Gibbs. Gibbs arrives in Atlanta and brings a young assistant named Jeff Jagodzinski. Gibbs' job is to revive a dormant Falcon team and bring life to its running game to take pressure off prize rookie Mike Vick.
The first game of that season, a mediocre SanFran team held Atlanta to 95 yards on 28 carries. Atlanta won the game and was praised for "sticking to the run." Atlanta won their second game and ran the ball much better. By the third game, Atlanta smoked an overmatched Arizona for 194 yards rushing on 30 carries, a 6.5 yard per carry average. Game four was more of the same, albeit a little less gouging, as Atlanta ran for 165 yards on 40 carries,averaging 4.1 yards per carry. This is what Alex Gibbs is all about. 4.1 yards per carry yields a first down every time. Move the chains with the running game in the NFL and you win."
This past season, your Houston Texans ranked 22nd in the league in rushing yards per game (99.1) and 22nd in yards per carry (3.8). Perhaps I'm going out on a limb here, but I feel confident predicting that those numbers are going to improve dramatically now that Gibbs is in town, regardless of who gets the carries at RB.
