In the first game, I think it'll be Waggner alongside Berry; maybe Rogan. Raines may be fast, but he is both green and small. Then after getting some game experience as subs in those first couple games, FS could well be claimed by either Myles or Jackson, but we'll just have to see how quickly they pick it up.
It looks to me like we are likely to start the season with at least one first-time starter among the db's, but seems like if you do that with two out of the four, you could be asking for trouble. Yet a daring coach might get away with it with the first game being WKU. If the starters against WKU were Berry, Rogan, Waggner, and Evans, I wouldn't feel too bad about that combo.
