NFL.com's Gil Brandt explains it very well in this article from the AJC:
http://blogs.ajc.com/atlanta-falcons-bl ... ead-coach/[quote]“Nick Saban told me that the (lowest) weight they could get him down to was 356 pounds,” Brandt said. “I think the guy tires. I’ll tell you what, you are going to have a hard time. . . these players that once they leave college and lead a more settled life when they get into the NFL, historically they gain weight.”
Cody tipped the scales at 370 pounds at the Senior Bowl.
“If you were assured you were going to be able to keep (his weight) down. . .he’d be alright,” Brandt said.[/quote0
