Chad Hall was released by the Chiefs today, so that they could add Kyle Williams. Kaepernick liked him in training camp and pre-season, he already knows our system, and if I recall, he had the most catches in training camp. Is it worth bringing him in? I don't think he could do much worse than the others (Boldin excepted). He would probably get cut after Crabtree returns, but he might be a good stop-gap for a couple weeks.
