The Rams Oline is not about getting better players. It's going to be about staying healthy and getting quality depth.
It is inevitable that some of the guys will go out for a while.
The main area of concern is LT. Blythe filled in very admirably at Center for Sullivan.

Should a potential starting LT slip to 23 on Draft day, I'd take him over any available edge rusher or ILB. With the pieces Wade now has, he can get very creative and get pass rush from a lot of places, and have a mediocre LB corps and still be an elite D. But LT is ALWAYS scary exposed. Whitworth goes down and we better have an adequate plan to back him up that doesn't include always lining up a TE next to him.
