They are undersized but they are not tackling at all.FWIW, I was listening to Chuck & Chernoff a few weeks ago and Chuck was talking about Tulane. He said "I've got a guy at Tulane who's 'about as close to the program as a guy can get'". (From which, I was inferring that he was referring to an assistant coach). He then went on to say, "Now I'm not saying it's going to happen but this guy tells me that they believe they will surprise Tech with their ability to handle the triple option."
He described the Tulane defense as undersized but fast and said it's easy to forget they were also a bowl team last year and this was a potential trap game for Tech.
