I have returned from taking two weeks off. Here are some thoughts on some San Francisco 49ers' news that transpired while I was away:Sherman blasts Crabtree again: Seattle cornerback Richard Sherman continued to take verbal shots at 49ers receiver Michael Crabtree. Sherman famously took shots at Crabtree after deflecting a Colin Kaepernick pass in the end zone intended for Crabtree in the final seconds of the NFC title game in January. It was intercepted, sealing the game for Seattle.
