Andrew Walter has gone from the Raiders to the Patriots in just one week's time and the differences are stark. "There's not a whole lot of similarities with this and the offense I've been in the past two years," he said. "I've been in a number of offenses in the pros, so you associate terms you're hearing now with what (you've known) from the past. Some of that does carry over, but I will say so far there hasn't been a ton." Walter sees an "explosive" offense in his early perusing of New England's book, and also feels positive vibes and a great atmosphere from his new team.
