Yeah, that's probably true.
I'd say that re-signing Zach Brown would help the LB situation.
No Spikes for sure. If I thought that Preston Brown could fetch a mid-round pick, then I'd say look for a trade, but I don't see that happening. They might have to go the Jim Schwartz method of simply hiding him in zone coverage when they need to--if he plays the Will spot and is the 1st LB off the field in nickel sets, he can probably contribute.
Ragland...sigh. Blokes will laser me for this, but I simply wasn't a Ragland guy. He's more athletic than he gets credit for, but I don't see a Kuechly or a Davis looking at him. Maybe he can drop down to 235ish LBs and acquit himself in coverage as you say...that would be a huge bonus.
You're reading him wrong methinks...I didn't see that as an indictment so much as a question of how they approached scheming against the opponent.
