Carson Palmer sent a public warning to Tom Brady that recovery from major knee surgery isn't just physical. Palmer suffered an injury in 2006 that was very similar to what Brady incurred last fall. "The biggest part was the mental block of the confidence of following though on your throws," said Palmer, according to the Los Angeles Times. "Still to this day I'm trying to get over this mental block. There's just somebody somewhere near you -- because your eyes are so focused downfield and you're looking at five different things in one play -- that there's somebody two yards away from you, two inches away from you, eight yards away from you, and you feel that."
