TT is tied at #18 for turnover margin at +4. ISU is tied at 61 for turnover margin at 0. TT didn't force any turnovers in their first 2 games of the season. That''s what help them beat OSU and, while technically not true, in my mind they beat Baylor.
Maybe they are just great at getting TOs or maybe they are just lucky. I rewatched the Baylor vs TTU game and the INT's that the Baylor's QB threw were just really bad passes, which is weird for him.
