With his sixth spring practice just one day away, LSU football coach Les Miles said Wednesday that changes in the team will range from practice drills to potential starting lineups.”We really saw a team improve significantly,” Miles said. “We have really good people, and it’s that factor of youth that’s saying, ‘Damn, I really want to be a part of this.’ We have enough youth in this team that it will bubble with competition.”One position last season where youth was a persisting factor was quarterback with then-sophomore Jordan Jefferson. Miles said rising junior Jarrett Lee and rising redshirt freshman Chris Garrett “will provide competition” for Jefferson, now a rising junior.”With a year under his belt, we can expect [Jefferson] to reap some of the rewards of his experiences,” Miles said. “He’s seen the position better than he has before, and he’ll continue to progress with throwing [the ball] away, not holding onto it and getting the formation lined up.”Miles said rising junior Stevan Ridley, rising senior Richard Murphy and rising redshirt freshman Michael Ford will “get the ball repeatedly” at running back. Murphy injured his knee against Vanderbilt in 2009 and did not return for the rest of the season.”He’s unbelievably ready. You should see him compete in the morning against Ford, Ridley, you name it,” Miles said. “The one thing we won’t let him do in spring is be tackled. I’m enjoying Ford’s academic improvement. That’s a great sign of maturity.”Defensively, Miles said he will stick with the scheme from last season with a few possible position adjustments.”We still very much enjoy the fact that we can get some push up front and big ole seams in there,” Miles said.Miles said rising senior Jai Eugene could move to safety, and rising sophomore defensive back Craig Loston will “vie for playing time.”On the coaching side, a vacancy still exists at the position of tight ends coordinator from when Don Yanowsky departed for Memphis.”I have interviewed a number of guys, and we feel there will be a great candidate forthcoming,” Miles said. “We will have taken good time to make a quality hire.”—-Contact Rachel Whittaker at [email protected]
