TE shouldn't make your comfortable. Same for LB, although not as bad as at least we have bodies there.
TE is a luxury in college football. I'm not going to get in a twist over it. While I wish we had one, an offense can work around weaknesses at TE. You don't even really need to have one if you don't want one. Defensive ends, OTOH, are kinda important.
As for LB, depth is a definite concern. I'm OK with the starters, though. I think that is a solid group. I don't want to think about what happens if Gillam gets hurt.
