Just a stray thought... I know the Chiefs signed Joe Mays to play alongside DJ, but that still just doesn't seem the strongest option.
I don't know if Tamba has ever played ILB, but he is bigger and heavier, probably stronger than Joe Mays
The 4 of the 3-4 would look like this....Dee Ford on the right side then DJ....then Tamba next and Houston on the left..
I thought it could be a mix and match, I know we have Nico Johnson (hope he rises to the top), Zombo, and a few others, just thought it might extend Tamba's career... mess with opposing O-line's etc.
Just a thought.
