Broncos coach John Fox said in an interview with CBSSports.com at the NFL owners meetings in Phoenix on Tuesday that second-year running back Ronnie Hillman has the chance to play a bigger role this season. "Our young guy is getting better," Fox said. "We’re really pleased with him. ... I thought for a rookie — if Ronnie Hillman went to a place where they just called a play and ran it, his transition would have probably been quicker than a guy that’s probably going to call one in 10 plays and nine of them are going to be passes and they’re exotic protections that are changed right there for a rookie to look at. Our style of offense didn’t help him much. I think it takes a year to develop a pro body. He is a guy at the end of the season weighed 189 pounds. He needs to be bigger and stronger and needs a full year to develop and train what I call a pro body. I think that will only help him.”
