Training camp helps the coaches as much as players, which is good because DC Perry Fewell needs time to learn how to use DT Marvin Austin. “He's different than the defensive tackles we have because he has legit speed and quickness to get off blocks,” Fewell said. “I think he can really cause some offensive linemen some problems with the things he can do.” Fewell said Austin is big, but doesn’t consider him out of shape.
