In my eyes:
Wegener = Marc Pelini
I don't think he's Pelini. Yes, he's small, but he's a much more athletic and powerful player. Think Caputo instead. That's not a bad thing.
In any case, Wegener is a 3 to play 2 guy, and will be getting academic scholarships and aid this year as a walk-on. He's not showing up until summer to maximize what he can get. My guess is that he's not playing this year unless all of the other options are bad.. I mean worst case can happen, but I think it's unlikely
Jurgens - size mostly and staying healthy - he's the guy they want though. Can he show up at 300 lbs?
Forbes - listed at just a bit bigger than Jurgens but looks bigger to my eyes. inexperienced, but a guy who looks to maul a bit and be athletic (like Hixson, the coaches seem to love his attitude)
Farniok - guess I see him as a backup, but he can play a bit
Miller - didn't hear as much about him this year (maybe Forbes slid ahead)
Hixson - would we move him if things were bad enough above? I don't think we need to, but maybe
Bland - would be hard to get him up to speed even if he gets here soon
Wegener - honestly, I see him as a RS this year.
I get the concerns, but I also have some faith in Austin, Duval and Ellis to get these guys where they need to be. We don't have an automatic starter, but there are at least 3 guys there that can be pretty good and maybe better than pretty good longer term
With the second year in the offense and what I think is an upgrade over Foster at LG, I think we'll have a better line this year. Lots of time before now and first game
