I started a thread a while back comparing our 2008 and 2009 opening day rosters. Here's an updated version. As you can see, our team is looking massively improved over where we were in 2008:
2008 - Thigpen/Huard/Croyle
2009 - Cassel
Cassel won 11 games in 2008. Thigpen and Huard won 1 apiece. Cassel is bigger, has a better arm, and is more accurate. Easy call.
Mike Cox is a good enough FB who shouldn't see a ton of work this year.
2008 - LJ/Battle/Charles/Savage
2009 - LJ/Battle/Charles/Williams
Basically the same. I think the big difference between 2008 and 2009 will be the level of LJ's effort. Now that he has a real HC and his contract isn't guarenteed, expect a Cory Dillon in NE-style rebirth.
2008 - Bowe/Bradley/Franklin/Webb
2009 - Bowe/Toomer/Engram/Bradley/Lelie
One of only compaints I've had this offseason is that we never really seemed to figure out what we're doing with out WR corps. It's better than 2008 corps, and I think Toomer and Engram are much needed sure hands, but it's still an area of concern.
2008 - Gonzalez
2009 - Ryan/Cottam/O'Connell
Our most obvious drop off in talent. Tony G. will be very missed. Ryan will beat out Cottam, I think, due to his experience, health, and blocking skills.
2008 - Albert/Waters/Niswanger/Jones/McIntosh
2009 - Albert/Waters/Alleman/Goff/Ndukwe
I'm assuming Alleman and Ndukwe end up beating out Niswanger, Richardson, and McIntosh (a safe bet). No question, the 2009 OL is better. I still think were a ways away from "good" though.
2008 - Boone/Dorsey/Tank/Hali
2009 - Dorsey/Edwards/Jackson/Magee
I'm guessing Edwards beats out Tank at NT, and that we have a pretty consistent rotation between Jackson, Dorsey, and Magee at DE. We aren't going to get a ton of sacks from our DL, but they at least won't be a sieve against the run.
2008 - DJ/Pat Thomas/Donnie
2009 - Hali/DJ/Zach Thomas/Vrabel
Big edge to 2009. Vrabel and Zach Thomas are a bit past their primes, but they're massive upgrades over Pat Thomas and the corpse of Donnie Edwards. Our reserves in Mays and Beisel are far better than D. Williams and Boiman.
2008 - Flowers/Carr/Page/Pollard
2009 - Flowers/Carr/Brown/Pollard
Not much of a change. I still think Brown beats out Page at FS (how can he not?!). Leggett and Page should be our main reserves.
Edge: Slight edge to 2009
2009 - Robinson/Charles
2009 - Unknown
I don't know who will win the starting KR or PR job, but they have to be better than Robinson/Charles at PR/KR.
Edge: Probably 2009
2008 - Barth/Colquitt
2009 - Succop/Colquitt
Barth wasn't bad at field goals shorter than 40 yards. But he had no range was bad at kickoffs. Succop gives us improvement there, and can at least attempt 45-50 yarders.
2008 - Herm/Gailey/Gunther
2009 - Haley/Gailey/Pendergast
Do you even have to ask?
Big Edge: 2009
We are a worse team at TE.
We remain unchanged at LT, LG, 1WR, HB, FB, and NT.
We have upgraded at QB, C, RG, RT, 2WR, OLB, LDE, ILB, FS, and K. Not to mention that Hali and Dorsey should improve in their new positions. And that our special teams have massively improved.
I still see us at 6-8 wins this season. Which is pretty good. Another great offseason, and we should be (at the minimum) contending for a playoff spot.
