Maybe I'm going to be proven wrong but I don't think Elder will get out of the second round. He's a future star in the NFL and people know it.
2nd - 3rd grade would be what I give him. Late 2nd to early 3rd round. His size will hurt him but he's not afraid to tackle, good tackler in space, great speed, COD...he's a very solid player but I think he's only going to measure about 5'9" at the combine.
