It's pretty simple. The Colts can not stop the run, and everybody, including the Texans, know it. The Pats were running all over the Colts D in the first half of their game, and for some reason abandoned the run. That's the reason why they lost to the Colts, same thing when the Pats lost to the Jets. Poor playcalling lost both those games, hell, we were in both games to the very end. Come playoff time, when the Colts have to face Tomlinson or Lewis or Taylor/Drew-Jones or Dillon/Maroney or Henry, and those teams will run through and around the Colts run D. Defense wins championships, and obviously the Colts don't have a good D.
