Here's a face-off we did a couple months back. It's on the subscriber server now but wasn't subscriber-only content at the time so you should still be able to access it either way.
Reed's value is pretty dependent on big plays. If you're scoring system values steady consistent tacklers, you assume some risk with Reed. He'll have some huge weeks and some stinkers.
The injury isn't an issue and the scheme shouldn't hurt him much. Like Polamalu, Reed's talent is such that he'll transcend the limitations of his scheme because he (and his coaches) gets him(self) in position to make plays.
