I agree with a lot of this.
I will say that I think Byrd to WR made some sense at the time the decision was made. Coming into the year, we had Sutton/Martin/Moseley/Foreman at CB, with Buchanan impressing in camp. That looks pretty good, especially since Foreman has had a solid year aside from a couple of very visible blunders. But Sutton and Foreman both spent significant time injured and Martin's head came off. Now you're trotting Moseley and Buchanan out against the other team's best WRs, which is a nightmare and was never the plan. So while I wouldn't have wanted Byrd moved to WR personally, I think that decision was at least defensible and has been exposed in hindsight because of extreme circumstances.
I agree with your stance on Warrior - yes, we'd have to live with some mistakes, but it's not like Kelly and Abernathy are setting a high standard at the position. Kelly lacks speed, Abernathy plays soft, and both blow plenty of assignments on their own. Sidenote: Kelly looked very athletic as a freshman. What happened? Put on too much muscle?
I'd love to hear an unvarnished explanation from the coaches on why Berry doesn't play offense. He's IMO a very average safety whose speed is offset by his slow instincts and he's not nearly as physical on defense as he is with the ball in his hands. What does he lack on offense that they're looking for?
As for Phillips, my impression was that he moved inside due to emergency. I expect him to move back to the edge after the season, especially since our two starting ends are gone.
