Ok, I know I'm starting to get fan tunnel vision, but when I look around the roster, things aren't as bad as I was expecting. I only have a couple minutes, so I am not going to go in depth, but will drop some thoughts and figure we can run with the conversation from there.
Offense:
QB: Clear question marks here.
RB/FB: Question marks, but with improving line, healthy White, McGahee and Fox's RB scheme, should be servicable or better (Fox claims Broncos will have the most sophisticated running game in the NFL this year). Hard to say where we are with FB. It was said that Fells might play some FB. Will we sign a true FB?
OL: Was it an ESPN insider that called it a strength and referred to them as one of the youngest and most athletic lines in the league, or something like that. I'm not sold yet, as the two second year players struggled often last year, and Franklin is an unknown.
WR: Lloyd looks to be in the same form as last year, based on camp reports, and Royal appears healthy and fast (reports again). This group can be anywhere from average to a strength, depending on what happens with Decker, Anderson, and the young guys. If DT comes back healthy, this group should eventually be a "strength"
TE: This was looking very week, but possibly up with the new signings. Based on the signings (big guys), it looks like there will be an emphasis blocking from the tight ends. Obviously, if Julius Thomas looks as good in games as he has shown in practice, he could make it an exciting position.
Defense:
DE. How will Doom fair moving back to end? How will Ayers play at end? They could be great speed rushers, or one or both of them could slip into a rotational spot (don't see Doom being relegated to pass rush spots only). In Hunter, Ayers and Beal we have three tweener type DE's, with Doom being more of a midget as some on here like to refer to him.
DT: It would seem that at the moment, the question is do our existing guys perform better moving back to a 4-3 and under Fox's tutelage. It's possible we will still pick up a DT or two, but at the moment, it doesn't look like any impact players have been added.
LB's: With Von Miller and DJ on the outside, I expect a lot of plays to be made from our OLB spots. Early reports on Miller are impressive, and we need the number two overall pick to make an impact right away. That leaves the big question at MLB and whether Irving or Mays can step up. Assuming Mays or Irving can be serviceable, this should be an area of strength unless Miller struggles as a rookie (which could easily happen).
S: Big questions here. With the release of Hill, that would indicate they probably are hoping Moore can start right away. He's impressed in practice. How much does Dawkins have left? Can McBath, McCarthy or Bruton play at starter level if Moore isn't ready? I would say there is upside potential here, but enough questions that it could be anywhere from weak to strength.
C: Wow, the Cox impregnation is a blow to this group. Even if he avoids jail, he surely will be playing distracted. Will the Broncos want to commit to him being a starter or major piece, knowing he may be gone? I assumed he would fight Goodman for the spot opposite Champ, but now I'm not sure. Obviously, Champ alone elevates the corners a bunch, since he allows coverage help to be rolled to the other side. However, Goodman is serviceable at best. I'm not sure Thompson is more than a dime back (although he showed nice flashes last year), and see Vaughn as more of a fill in/dime guy. So, I'm not really sure where to rate this. I don't see this being a weakness, but there are enough questions for it not to be a strength.
So, there are definitely questions up and down the starting lineup, but I don't see many "we are going to be awful in this area" spots.
