Yeah, there's no way anyone signs him for $4M/yr. Also, my guess is Raji doesn't sign a one year deal either. My guess is 2y/$4M with another $1M in incentives (assuming he checks out physically). Until this injury he was playing full seasons and camp reports indicated he was looking as good as ever back at NT. Whether TT brings him back depends on how the D plays without him, and especially if Boyd/Pennel/Guion can take over.
It's a blow to the DL but not so bad they can't recover. They will need Raji's replacements to stay healthy, which might be asking a lot.
