Is Bush having a hard time adjusting to the NFL?

Apparently the deal is, they are keying on Bush. This is why everyone else on our team is putting up good stats. When Bush gets the ball, he has 11 guys on him. When he's at receiver, he has 11 guys covering him. When he's on the sideline, so is the defense. This is why our pass protection has been so good, If Bush were playing quarterback, they'd actually rush the passer. He did throw one pass and it was intercepted. That's because they had 5 1/2 guys rushing him and 5 1/2 guys down there to go for the INT.
