Back for his 5th season, Reggie Gilbert will anchor the defensive line. His size and leadership will help in the trenches. He's a guy who probably won't come off the field much. Arizona picked up JUCO transfer Timmy Hamilton, and he should be able to have an impact immediately. There hasn't been much talk of him up until now, but he would be a nice surprise to provide the line with depth.
Marcus Griffin, a former 4-star recruit, has the size that Rich Rodriguez is looking for. At 6-0 300lbs, he's the biggest defensive linemen that has been with the program.
