I would think the ILB thing is certainly a thorn in his side. You could certainly pick up on that in Demovsky's article.
As far as a trade, I'd think his cap numbers would make that difficult...and as for REALLY being hurt, um. I'm skeptical.
Had this happened pre-Seattle comments, I would be slightly annoyed (since he just had the knee) and chalk it up to being cautious with vets, such as with Sitton. After his #1/a TE exhaled on my knee stuff, well I'm a little more disgruntled when reading this.
