‘University at Buffalo products Drew Haddad and Josh Roth were among five players who were assigned to the Buffalo Bills’ developmental squad on Monday. Haddad was taken in the seventh round and hoped to catch on with the Bills as a punt returner and receiver. He returned three punts for 22 yards in the preseason. He also had three catches for 22 yards. Roth had one catch for 11 yards. He did not carry the ball. "It’s a big help for kids in the developmental stage," Bills coach Wade Phillips said. "I think they can learn a whole lot in that situation."’
