Josh McDaniels went back to his roots to try to find some help for his inexperienced defensive line.
Smith is 6-foot-3, 308 pounds and he will add some beef to the defensive front. Denver's front three is one of its biggest question marks. Smith is expected to be a reserve in Denver. The current starters are ends Kenny Peterson and Ryan McBean and nose tackle Ronald Fields. The threesome has a combined two NFL starts in the past two seasons.
Smith was a backup in New England, where McDaniels was the offensive coordinator. McDaniels has brought several players from New England to Denver since being hired in January.
