QBs coach Jim Zorn ran a little different version of the old playground game “man in the middle” with his four QBs in Thursday’s OTA. One QB stood in the middle with Zorn and the other QBs circled around him, throwing large exercise balls at the passer in the middle. Matt Cassel was fluid in dodging the balls. Not so with youngster Ricky Stanzi, who took several head-on hits.
