Right now the Aggie defensive line is in a state of flux. No one can tell you with any kind of certainty who is going to start against Rice on August 31.
If you look at the depth chart, the current starter at nose guard is redshirt freshman Kimo Tipoti. He spent the 2012 season and the beginning of spring practice playing offensive guard.
There are questions that need to be answered before anything can be sorted out. The first question is whether or not Kirby Ennis will be ready to play after undergoing offseason surgery.
If the senior is back to 100 percent, then he will start at nose guard. Right now, sophomore Alonzo Williams is listed as the starter at defensive tackle.
There are a group of true freshman defensive linemen who will be competing for playing time at defensive tackle. If either Hardreck Walker, Justin Manning, Isaiah Golden or Jordan Points prove capable of holding up at defensive tackle, you could see Williams moving back over to strong-side defensive end.
It appears that Julien Obioha is going to make the move over to the weak-side defensive end position. If Obioha is able to provide the Ags a consistent pass rush, then he will stay on the weak side and either Williams or redshirt junior Gavin Stansbury will start on the strong side.
Incoming freshman Daeshon Hall will also get a look on the weak side. He is probably too thin at 6'6" and 220 pounds to see significant time in the SEC right now, but he will see the field in 2013.
The fact that Aggie defensive coordinator Mark Snyder likes to employ multiple formation and will likely open in an odd-man front against Rice and Sam Houston State complicates matters further.
There are numerous questions on the Ags' defensive line, and some of them will not be answered until September 14 when the Ags take on Alabama.
