I agree on Hardee. The guy played over 360 snaps on ST last year. That has value, likely more value to the team than a 6th or 7th CB who does not give us what Hardee does on specials. I think he is safe.
Edoga - remains to be seen. Will be fighting for his position in the summer -- would like to see him beat out McDermott for a back-up tackle spot. Would not be shocked either way, but I would think if they are close, the 25 year old gets the edge ahead of the 30 year old.
I do expect Hamsah will be on the team. I think he has another year to prove he belongs.
Agree with you that Huff could be odd man out if the oethr edges stay healty through camp. Would be a good PS candidate (as would Hamsah if he is cut).
