Defense, worse before it gets better?

I'm not abandoning this season by a long shot. I thought it woudl be 6 wins, and I still think it will be. I thought next season we'd be bowling and I still think... Ok, I'm not at all so sure about that now. But like I mentioned in September, I've never followed College football before, so I'm not used to looking at Roster turnover. It scares the hell out of me lol.
The offense looks set right now. I mean, we lose Chase and Pellerin, but we still have Sanders and Givens, not to mention Sledge and a host of youngs guys for depth. The entire starting O-line returns, and we'll have Martin/Mapps/Henderson to carry the ball. We lose Kennedy at TE, but I believe that Chase will excell at that role next season.
The offense should improve dramatically next season.
The defense though...
Who is going to start at DT next season? The line is going to be horribly depleted isn't it? Muse will return on one end position, but outside of that it's going to be anyone's guess. Hawkings, McCarry and Carrington will be back to man the LB spots, and we may be ok at CB with Lowery, McCaan Lindley and Haynes... But what's going to happen when Joe Sturdivant leaves? Who's going to man the Safety positions? It just looks to me like we're going to have gaping holes at the DT and S positions. Is it normal in college football to have to cross your fingers and make the leap of faith that someone will step up next year? Or will there be a host of JuCo kids coming in to fill in some blanks?
Walk me throught the process here, because it's been a [horrible] weekend to be a Mustang/Charger fan.
