On the position battles...
I don't see any changes in the starting lineup anytime soon. I don't think Lavalais is going to lose his starting job. Will he lose playing time? Perhaps as Lake, Babs, and Shrop take bigger chunks of time at DT, but I don't see any of them taking his starting job away from him.
CB? Again, I doubt Webster loses his job until at least a month or so into the season. And that's going to depend on how many big plays J-Will makes early on.
Unless Norwood truly is something special this summer, or the Falcons find a way to ship off Duckett, I doubt we won't be seeing #45 get the meat of the carries behind Dunn.
As for Claxton, it's obvious Gibbs likes him. The Broncos drafted him while Gibbs was advisor there and the Falcons claimed him last summer when they cut him. I don't see him starting, but he could supplant King as the top backup off the bench with a good summer. As of now, King is the guy the team turns to whenever any of the interior linemen go down.
Agree that Lavalais will start teh year - his problem last year was his conditioning and he ran out of gas at the end of the season.
Williams will ride the pine and be the nicle/dime until the rookie can demonstrate he is capable at the higher speed (injury can speed that up). Generally rookie DBs don't make good starters (svae the superstars, of course).
I think Norwood will progress faster because i don't have much faith in Duckett. Duckeet may be in his contract year, but he just has not shown much and reall tanked last year.
The OLine? your guess is as good as mine. Whatever works.
