Chiefs sign NT Kelly Gregg (1 year): A- Grade
This is a pretty good signing. Turning 35 in November, Kelly Gregg is not the player he once was, but should still be an effective run stopper. He'll offer a cheap upgrade at nose tackle and keep the seat warm for rookie Jerrell Powe.
(I tend to ignore the opinion of this site most of the time due to their ignorance and perceived hatred of the Chiefs for some reason, but this brings them up a notch in my book)
