LSU safety Craig Loston isn't the guy you want to meet in an alley, dark or otherwise. That's the place on the football field where he does his best work.

Loston has never shied away from making the big hit coming up fast from the secondary on running backs. What he'd like to show NFL officials, coaches and scouts at the Senior Bowl this week is that he's got the cover skills to do it all in the secondary.

Practices continue this week with the game set for Saturday at 3 p.m. in Ladd-Peebles Stadium.

"Being able to run the alley is my strength," Loston said, referring to run support. "I need to show I can cover one-on-one.

"I feel like I've done a good job of that so far. There are some fast, talented receivers out here. I'm focused on staying with my man, step-for-step."

Loston, who was measured at 6-feet and 214 pounds on Monday, has never been afraid to give up his body for a tackle, sometimes to his detriment. He battled injuries through his first three seasons, including a concussion on special teams in 2011 that limited his rotations with Eric Reid and Brandon Taylor. He started 21 games during the past two seasons with 112 tackles in that span.

In his last college game he had a team-leading six tackles, three of them for loss and one of which was a sack in LSU's 21-14 Outback Bowl victory against Iowa. He also collected his seventh career interception.

Loston has gotten some notice in the first two days of practice. Jacksonville Jaguars coach Gus Bradley, who is guiding the South team, has been working extensively on the defensive side and singled out Loston for some praise Tuesday.

"He's done a nice job in coverage," Bradley said. "He had a couple of nice plays and did a nice job in seven-on-seven. You can tell he loves the game. He showed good range and picks things up quickly."

Loston concurred that the NFL schemes brought in by Bradley and his staff haven't been a mystery. He said playing and practicing under John Chavis for five seasons has prepared him well and that he was able to get into the flow quickly.

Both Loston and Tiger linebacker Lamin Barrow have been running with the first South defense.

"I felt like I was at home, I didn't see much difference," Loston said. "It's the same things we do at LSU, just some different terminology. Chief (Chavis) has done a great job getting us ready for a position like this."

Being ready is a long way from getting drafted, Loston said. He'd been working out at LSU before the Senior Bowl week, trying to improve his cover skills through speed and agility work. He isn't high on the draft radar like former teammate Reid, who went in the first round, but could move up to a second-day pick, which includes rounds two and three of the May draft.
